TJ-II:Magnetic configuration

2026-10-13T12:48:20Z

Admin:

The magnetic configuration of [[TJ-II]] in vacuum is completely determined by the currents flowing through the [[TJ-II:Coil system|external coils]].
Magnetic configurations are labelled as 'xxx_yy_zz', where
* 'xxx': 10 times the current (in kA) in the circular coil
* 'yy': 10 times the current (in kA) in the helical coil
* 'zz': 10 times the current (in kA) in the vertical field coils
The current in the toroidal field coils is not specified, as its value is adjusted to guarantee central absorption of the [[TJ-II:Electron Cyclotron Resonant Heating|Electron Cyclotron Resonant Heating]] source (requiring a specific 'resonant' value of the magnetic field at the magnetic axis, <math>B_{reson}</math>).

[[File:Flexibility TJ-II.png|300px|thumb|right|Flexibility diagram of TJ-II magnetic configurations. Several lines of constant rotational transform are highlighted and labelled with the corresponding edge <math>\iota/2\pi</math>-value.]]
TJ-II has considerable configurational flexibility, as observed in the 'flexibility diagram'<ref>E. Ascasíbar, T. Estrada, F. Castejón, A. López-Fraguas, I. Pastor, J. Sánchez, U. Stroth, J. Qin and TJ-II Team, ''Magnetic configuration and plasma parameter dependence of the energy confinement time in ECR heated plasmas from the TJ-II stellarator'', [[doi:10.1088/0029-5515/45/4/009|Nucl. Fusion '''45''' (2005) 276–284]]</ref>.
The sum <math>I_{CC}+I_{HX}</math> is an important factor determining the size of the plasma, and should not be too small. Thus, reasonably-sized plasmas are limited to the upper right triangle of this diagram.
Some of this flexibility space has been explored, as in the 'magnetic well scan' experiments<ref>A. de Aguilera, F. Castejón, E. Ascasíbar, et al. ''Magnetic well scan and confinement in the TJ-II stellarator'', [[doi:10.1088/0029-5515/55/11/113014|Nucl. Fusion, 55(11):113014, 2015]]</ref>.
More recently, the [[rotational transform]] in the plasma edge region was found to be of importance for [[H-mode|L-H]] confinement transitions<ref>B. P. van Milligen, T. Estrada, B. Carreras, L. García, and TJ-II Team. ''Importance of the rotational transform for L–H transitions in the TJ-II stellarator'', [[doi:10.3390/plasma7020024|Plasma, 7(2):446–464, 2024]].</ref>.

TJ-II:Magnetic configuration

2026-10-13T09:52:53Z

Admin: /* Flexibility */

The magnetic configuration of [[TJ-II]] in vacuum is completely determined by the currents flowing through the [[TJ-II:Coil system|external coils]].
Magnetic configurations are labelled as 'xxx_yy_zz', where
* 'xxx': 10 times the current (in kA) in the circular coil
* 'yy': 10 times the current (in kA) in the helical coil
* 'zz': 10 times the current (in kA) in the vertical field coils
The current in the toroidal field coils is not specified, as its value is adjusted to guarantee central absorption of the [[TJ-II:Electron Cyclotron Resonant Heating|Electron Cyclotron Resonant Heating]] source (requiring a specific 'resonant' value of the magnetic field at the magnetic axis, <math>B_{reson}</math>).

== Flexibility ==

[[File:Flexibility TJ-II.png|300px|thumb|right|Flexibility diagram of TJ-II magnetic configurations. Several lines of constant rotational transform are highlighted and labelled with the corresponding edge <math>\iota/2\pi</math>-value.]]
TJ-II has considerable configurational flexibility, as observed in the 'flexibility diagram'<ref>E. Ascasíbar, T. Estrada, F. Castejón, A. López-Fraguas, I. Pastor, J. Sánchez, U. Stroth, J. Qin and TJ-II Team, ''Magnetic configuration and plasma parameter dependence of the energy confinement time in ECR heated plasmas from the TJ-II stellarator'', [[doi:10.1088/0029-5515/45/4/009|Nucl. Fusion '''45''' (2005) 276–284]]</ref>.
The sum <math>I_{CC}+I_{HX}</math> is an important factor determining the size of the plasma, and should not be too small. Thus, reasonably-sized plasmas are limited to the upper right triangle of this diagram.
Some of this flexibility space has been explored, as in the 'magnetic well scan' experiments<ref>A. de Aguilera, F. Castejón, E. Ascasíbar, et al. ''Magnetic well scan and confinement in the TJ-II stellarator'', [[doi:10.1088/0029-5515/55/11/113014|Nucl. Fusion, 55(11):113014, 2015]]</ref>.
More recently, the [[rotational transform]] in the plasma edge region was found to be of importance for [[H-mode|L-H]] confinement transitions<ref>B. P. van Milligen, T. Estrada, B. Carreras, L. García, and TJ-II Team. ''Importance of the rotational transform for L–H transitions in the TJ-II stellarator'', [[doi:10.3390/plasma7020024|Plasma, 7(2):446–464, 2024]].</ref>.

== Description of the project ==

The general goal of the present proposal is to investigate the interaction of turbulence, plasmas flows and the magnetic topology and determine the impact of the resulting complex interactions on plasma transport. This topic could be important for ITER and DEMO.
To reach this goal, we need to reach the following objectives:
# Development of novel low noise electronics in vacuum and test it to obtain a better SNR than the actual one with the help of Ciemat electronics team. This upgrade is essential to be able to measure phase relations between fluctuating fields and understand their mutual interaction.
# Study the impact of the magnetic configuration on turbulent properties. We expect to find that the location of major rational surfaces plays a significant role in radial transport.
# Study the impact of confinement transitions on turbulence, and flows on plasma turbulence.




== Main results ==

El proyecto ha permitido avanzar significativamente en la comprensión de los mecanismos que regulan la turbulencia y la transición al régimen de alto confinamiento (L-H) en el stellarator TJ-II, un aspecto clave para el desarrollo de la energía de fusión. Aprovechando la flexibilidad del dispositivo para modificar con precisión la configuración magnética, se han realizado experimentos pioneros que han puesto de manifiesto la influencia de las superficies racionales y de la corriente neta del plasma sobre las propiedades turbulentas y el confinamiento.

Entre los principales resultados destaca la identificación de la intermitencia como un nuevo parámetro para caracterizar la turbulencia, demostrando su sensibilidad tanto a la configuración magnética como a los flujos de plasma. Asimismo, mediante experimentos con variaciones dinámicas de la configuración magnética se ha establecido una relación directa entre la evolución temporal de la turbulencia y la presencia de superficies racionales de bajo orden.

El proyecto también ha demostrado que la transición L-H y la mejora del confinamiento dependen de forma sistemática de la corriente neta del plasma y, por tanto, de la configuración magnética. El análisis combinado de experimentos y simulaciones de turbulencia MHD resistiva ha permitido proponer mecanismos físicos que explican esta dependencia, relacionados con la distribución de superficies racionales y la generación de flujos zonales capaces de suprimir la turbulencia.

Estos resultados contribuyen a mejorar la comprensión de los procesos fundamentales que determinan el confinamiento del plasma y proporcionan nuevos criterios para optimizar el funcionamiento de futuros dispositivos de fusión, reforzando el liderazgo científico en el ámbito del confinamiento magnético.

TJ-II:Magnetic configuration

2026-10-10T18:56:04Z

Admin: /* Flexibility */

The magnetic configuration of [[TJ-II]] in vacuum is completely determined by the currents flowing through the [[TJ-II:Coil system|external coils]].
Magnetic configurations are labelled as 'xxx_yy_zz', where
* 'xxx': 10 times the current (in kA) in the circular coil
* 'yy': 10 times the current (in kA) in the helical coil
* 'zz': 10 times the current (in kA) in the vertical field coils
The current in the toroidal field coils is not specified, as its value is adjusted to guarantee central absorption of the [[TJ-II:Electron Cyclotron Resonant Heating|Electron Cyclotron Resonant Heating]] source (requiring a specific 'resonant' value of the magnetic field at the magnetic axis, <math>B_{reson}</math>).

[[File:Flexibility TJ-II.png|300px|thumb|right|Flexibility diagram of TJ-II magnetic configurations. Several lines of constant rotational transform are highlighted and labelled with the corresponding edge <math>\iota/2\pi</math>-value.]]
TJ-II has considerable configurational flexibility, as observed in the 'flexibility diagram'<ref>E. Ascasíbar, T. Estrada, F. Castejón, A. López-Fraguas, I. Pastor, J. Sánchez, U. Stroth, J. Qin and TJ-II Team, ''Magnetic configuration and plasma parameter dependence of the energy confinement time in ECR heated plasmas from the TJ-II stellarator'', [[doi:10.1088/0029-5515/45/4/009|Nucl. Fusion '''45''' (2005) 276–284]]</ref>.
Some of this flexibility space has been explored, as in the 'magnetic well scan' experiments<ref>A. de Aguilera, F. Castejón, E. Ascasíbar, et al. ''Magnetic well scan and confinement in the TJ-II stellarator'', [[doi:10.1088/0029-5515/55/11/113014|Nucl. Fusion, 55(11):113014, 2015]]</ref>.
More recently, the [[rotational transform]] in the plasma edge region was found to be of importance for [[H-mode|L-H]] confinement transitions<ref>B. P. van Milligen, T. Estrada, B. Carreras, L. García, and TJ-II Team. ''Importance of the rotational transform for L–H transitions in the TJ-II stellarator'', [[doi:10.3390/plasma7020024|Plasma, 7(2):446–464, 2024]].</ref>.

TJ-II:Magnetic configuration

2026-10-08T09:12:12Z

Admin: /* Flexibility */

The magnetic configuration of [[TJ-II]] in vacuum is completely determined by the currents flowing through the [[TJ-II:Coil system|external coils]].
Magnetic configurations are labelled as 'xxx_yy_zz', where
* 'xxx': 10 times the current (in kA) in the circular coil
* 'yy': 10 times the current (in kA) in the helical coil
* 'zz': 10 times the current (in kA) in the vertical field coils
The current in the toroidal field coils is not specified, as its value is adjusted to guarantee central absorption of the [[TJ-II:Electron Cyclotron Resonant Heating|Electron Cyclotron Resonant Heating]] source (requiring a specific 'resonant' value of the magnetic field at the magnetic axis, <math>B_{reson}</math>).

[[File:Flexibility TJ-II.png|300px|thumb|right|Flexibility diagram of TJ-II magnetic configurations. Several lines of constant rotational transform are highlighted and labelled with the corresponding edge <math>\iota/2\pi</math>-value.]]
TJ-II has considerable configurational flexibility, as observed in the 'flexibility diagram'<ref>E. Ascasíbar, T. Estrada, F. Castejón, A. López-Fraguas, I. Pastor, J. Sánchez, U. Stroth, J. Qin and TJ-II Team, ''Magnetic configuration and plasma parameter dependence of the energy confinement time in ECR heated plasmas from the TJ-II stellarator'', [[doi:10.1088/0029-5515/45/4/009|Nucl. Fusion '''45''' (2005) 276–284]]</ref>.
Some of this flexibility space has been explored, as in the 'magnetic well scan' experiments<ref>A. de Aguilera, F. Castejón, E. Ascasíbar, et al. ''Magnetic well scan and confinement in the TJ-II stellarator'', [[doi:10.1088/0029-5515/55/11/113014|Nucl. Fusion, 55(11):113014, 2015]]</ref>.
More recently, the rotational transform in the plasma edge region was found to be of importance for L-H confinement transitions<ref>B. P. van Milligen, T. Estrada, B. Carreras, L. García, and TJ-II Team. ''Importance of the rotational transform for L–H transitions in the TJ-II stellarator'', [[doi:10.3390/plasma7020024|Plasma, 7(2):446–464, 2024]].</ref>.

TJ-II:Magnetic configuration

2026-10-07T16:29:20Z

Admin:

The magnetic configuration of [[TJ-II]] in vacuum is completely determined by the currents flowing through the [[TJ-II:Coil system|external coils]].
Magnetic configurations are labelled as 'xxx_yy_zz', where
* 'xxx': 10 times the current (in kA) in the circular coil
* 'yy': 10 times the current (in kA) in the helical coil
* 'zz': 10 times the current (in kA) in the vertical field coils
The current in the toroidal field coils is not specified, as its value is adjusted to guarantee central absorption of the [[TJ-II:Electron Cyclotron Resonant Heating|Electron Cyclotron Resonant Heating]] source (requiring a specific 'resonant' value of the magnetic field at the magnetic axis, <math>B_{reson}</math>).

[[File:Flexibility TJ-II.png|300px|thumb|right|Flexibility diagram of TJ-II magnetic configurations. Several lines of constant rotational transform are highlighted and labelled with the corresponding central <math>\iota/2\pi</math>-value.]]
TJ-II has considerable configurational flexibility, as observed in the 'flexibility diagram'<ref>E. Ascasíbar, T. Estrada, F. Castejón, A. López-Fraguas, I. Pastor, J. Sánchez, U. Stroth, J. Qin and TJ-II Team, ''Magnetic configuration and plasma parameter dependence of the energy confinement time in ECR heated plasmas from the TJ-II stellarator'', [[doi:10.1088/0029-5515/45/4/009|Nucl. Fusion '''45''' (2005) 276–284]]</ref>.
Some of this flexibility space has been explored, as in the 'magnetic well scan' experiments<ref>A. de Aguilera, F. Castejón, E. Ascasíbar, et al. ''Magnetic well scan and confinement in the TJ-II stellarator'', [[doi:10.1088/0029-5515/55/11/113014|Nucl. Fusion, 55(11):113014, 2015]]</ref>.
More recently, the rotational transform in the plasma edge region was found to be of importance for L-H confinement transitions<ref>B. P. van Milligen, T. Estrada, B. Carreras, L. García, and TJ-II Team. ''Importance of the rotational transform for L–H transitions in the TJ-II stellarator'', [[doi:10.3390/plasma7020024|Plasma, 7(2):446–464, 2024]].</ref>.

TJ-II:Magnetic configuration

2026-10-07T16:26:24Z

Admin:

The magnetic configuration of [[TJ-II]] in vacuum is completely determined by the currents flowing through the [[TJ-II:Coil system|external coils]].
Magnetic configurations are labelled as 'xxx_yy_zz', where
* 'xxx': 10 times the current (in kA) in the circular coil
* 'yy': 10 times the current (in kA) in the helical coil
* 'zz': 10 times the current (in kA) in the vertical field coils
The current in the toroidal field coils is not specified, as its value is adjusted to guarantee central absorption of the [[TJ-II:Electron Cyclotron Resonant Heating|Electron Cyclotron Resonant Heating]] source (requiring a specific 'resonant' value of the magnetic field on the magnetic axis, <math>B_{reson}</math>).

[[File:Flexibility TJ-II.png|300px|thumb|right|Flexibility diagram of TJ-II magnetic configurations. Several lines of constant rotational transform are highlighted and labelled with the corresponding central <math>\iota/2\pi</math>-value.]]
TJ-II has considerable configurational flexibility, as observed in the 'flexibility diagram'<ref>E. Ascasíbar, T. Estrada, F. Castejón, A. López-Fraguas, I. Pastor, J. Sánchez, U. Stroth, J. Qin and TJ-II Team, ''Magnetic configuration and plasma parameter dependence of the energy confinement time in ECR heated plasmas from the TJ-II stellarator'', [[doi:10.1088/0029-5515/45/4/009|Nucl. Fusion '''45''' (2005) 276–284]]</ref>.
Some of this flexibility space has been explored, as in the 'magnetic well scan' experiments<ref>A. de Aguilera, F. Castejón, E. Ascasíbar, et al. ''Magnetic well scan and confinement in the TJ-II stellarator'', [[doi:10.1088/0029-5515/55/11/113014|Nucl. Fusion, 55(11):113014, 2015]]</ref>.
More recently, the rotational transform in the plasma edge region was found to be of importance for L-H confinement transitions<ref>B. P. van Milligen, T. Estrada, B. Carreras, L. García, and TJ-II Team. ''Importance of the rotational transform for L–H transitions in the TJ-II stellarator'', [[doi:10.3390/plasma7020024|Plasma, 7(2):446–464, 2024]].</ref>.

TJ-II:Magnetic configuration

2026-10-07T16:25:16Z

Admin:

The magnetic configuration of [[TJ-II]] in vacuum is completely determined by the currents flowing through the [[TJ-II:Coil system|external coils]].
Magnetic configurations are labelled as 'xxx_yy_zz', where
* 'xxx': 10 times the current (in kA) in the circular coil
* 'yy': 10 times the current (in kA) in the helical coil
* 'zz': 10 times the current (in kA) in the vertical field coils
The current in the toroidal field coils is not specified, as its value is adjusted to guarantee central absorption of the [[TJ-II:Electron Cyclotron Resonant Heating|Electron Cyclotron Resonant Heating]] source (requiring a specific 'resonant' value of the magnetic field on the magnetic axis, <math>B_{reson}</math>).

[[File:Flexibility TJ-II.png|300px|thumb|right|Flexibility diagram of TJ-II magnetic configurations. Several lines of constant rotational transform are highlighted and labelled with the corresponding central <math>\iota/2\pi</math>-value.]]
TJ-II has considerable configurational flexibility, as observed in the 'flexibility diagram'<ref>E. Ascasíbar, T. Estrada, F. Castejón, A. López-Fraguas, I. Pastor, J. Sánchez, U. Stroth, J. Qin and TJ-II Team, ''Magnetic configuration and plasma parameter dependence of the energy confinement time in ECR heated plasmas from the TJ-II stellarator'', [[doi:10.1088/0029-5515/45/4/009|Nucl. Fusion '''45''' (2005) 276–284]]</ref>.
Some of this flexibility space has been explored, as in the 'magnetic well scan' experiments<ref>A. de Aguilera, F. Castejón, E. Ascasíbar, et al. ''Magnetic well scan and confinement in the TJ-II stellarator'', [[doi:10.1088/0029-5515/55/11/113014|Nucl. Fusion, 55(11):113014, 2015]]</ref>.
More recently, the rotational transform in the plasma edge region was found to be of importance for L-H confinement transitions<ref>B. P. van Milligen, T. Estrada, B. Carreras, L. García, and TJ-II Team. ''Importance of the rotational transform for L–H transitions in the TJ-II stellarator'', [[doi:10.3390/plasma7020024|Plasma, 7(2):446–464, 2024]].</ref>.

TJ-II:Magnetic configuration

2026-10-07T14:30:02Z

Admin: /* Flexibility */

The magnetic configuration of [[TJ-II]] in vacuum is completely determined by the currents flowing through the [[TJ-II:Coil system|external coils]].
Magnetic configurations are labelled as 'xxx_yy_zz', where
* 'xxx': 10 times the current (in kA) in the circular coil
* 'yy': 10 times the current (in kA) in the helical coil
* 'zz': 10 times the current (in kA) in the vertical field coils
The current in the toroidal field coils is not specified, as its value is adjusted to guarantee central absorption of the [[TJ-II:Electron Cyclotron Resonant Heating|Electron Cyclotron Resonant Heating]] source (requiring a specific 'resonant' value of the magnetic field on the magnetic axis, <math>B_{reson}</math>).

[[File:Flexibility TJ-II.png|300px|thumb|right|Flexibility diagram of TJ-II magnetic configurations. Several lines of constant rotational transform are highlighted and labelled with the corresponding central <math>\iota/2\pi</math>-value.]]
TJ-II has considerable configurational flexibility, as observed in the 'flexibility diagram'<ref>E. Ascasíbar, T. Estrada, F. Castejón, A. López-Fraguas, I. Pastor, J. Sánchez, U. Stroth, J. Qin and TJ-II Team, ''Magnetic configuration and plasma parameter dependence of the energy confinement time in ECR heated plasmas from the TJ-II stellarator'', [[doi:10.1088/0029-5515/45/4/009|Nucl. Fusion '''45''' (2005) 276–284]]</ref>.
Some of this flexibility space has been explored, as in the 'magnetic well scan' experiments<ref>A. de Aguilera, F. Castejón, E. Ascasíbar, et al. ''Magnetic well scan and confinement in the TJ-II stellarator'', [[doi:10.1088/0029-5515/55/11/113014|Nucl. Fusion, 55(11):113014, 2015]]</ref>.
More recently, the rotational transform was found to be of importance for L-H confinement transitions<ref>B. P. van Milligen, T. Estrada, B. Carreras, L. García, and TJ-II Team. ''Importance of the rotational transform for L–H transitions in the TJ-II stellarator'', [[doi:10.3390/plasma7020024|Plasma, 7(2):446–464, 2024]].</ref>.

TJ-II:Magnetic configuration

2026-10-07T14:27:31Z

Admin: /* Flexibility */

The magnetic configuration of [[TJ-II]] in vacuum is completely determined by the currents flowing through the [[TJ-II:Coil system|external coils]].
Magnetic configurations are labelled as 'xxx_yy_zz', where
* 'xxx': 10 times the current (in kA) in the circular coil
* 'yy': 10 times the current (in kA) in the helical coil
* 'zz': 10 times the current (in kA) in the vertical field coils
The current in the toroidal field coils is not specified, as its value is adjusted to guarantee central absorption of the [[TJ-II:Electron Cyclotron Resonant Heating|Electron Cyclotron Resonant Heating]] source (requiring a specific 'resonant' value of the magnetic field on the magnetic axis, <math>B_{reson}</math>).

[[File:Flexibility TJ-II.png|300px|thumb|right|Flexibility diagram of TJ-II magnetic configurations. Several lines of constant rotational transform are highlighted and labelled with the corresponding central <math>\iota/2\pi</math>-value.]]
TJ-II has considerable configurational flexibility, as observed in the 'flexibility diagram'<ref>E. Ascasíbar, T. Estrada, F. Castejón, A. López-Fraguas, I. Pastor, J. Sánchez, U. Stroth, J. Qin and TJ-II Team, ''Magnetic configuration and plasma parameter dependence of the energy confinement time in ECR heated plasmas from the TJ-II stellarator'', [[doi:10.1088/0029-5515/45/4/009|Nucl. Fusion '''45''' (2005) 276–284]]</ref>.
Some of this flexibility space has been explored, as in the 'magnetic well scan' experiments<ref>A. de Aguilera, F. Castejón, E. Ascasíbar, et al. ''Magnetic well scan and confinement in the TJ-II stellarator'', [[doi:10.1088/0029-5515/55/11/113014|Nucl. Fusion, 55(11):113014, 2015]]</ref>.

TJ-II:Magnetic configuration

2026-10-07T14:06:17Z

Admin:

The magnetic configuration of [[TJ-II]] in vacuum is completely determined by the currents flowing through the [[TJ-II:Coil system|external coils]].
Magnetic configurations are labelled as 'xxx_yy_zz', where
* 'xxx': 10 times the current (in kA) in the circular coil
* 'yy': 10 times the current (in kA) in the helical coil
* 'zz': 10 times the current (in kA) in the vertical field coils
The current in the toroidal field coils is not specified, as its value is adjusted to guarantee central absorption of the [[TJ-II:Electron Cyclotron Resonant Heating|Electron Cyclotron Resonant Heating]] source (requiring a specific 'resonant' value of the magnetic field on the magnetic axis, <math>B_{reson}</math>).

TJ-II:Magnetic configuration

2026-10-07T13:19:23Z

Admin:

The magnetic configuration of [[TJ-II]] in vacuum is completely determined by the currents flowing through the [[TJ-II:Coil system|external coils]].
Magnetic configurations are labelled as 'xxx_yy_zz', where
* 'xxx': 10 times the current (in kA) in the circular coil
* 'yy': 10 times the current (in kA) in the helical coil
* 'zz': 10 times the current (in kA) in the vertical field coils
The current in the toroidal field coils is not specified, as its value is adjusted to guarantee central absorption of the [[TJ-II:Electron Cyclotron Resonant Heating|Electron Cyclotron Resonant Heating]] source (requiring a specific value of the magnetic field on the magnetic axis).

Admin: /* Description */

[[File:TJII_model.jpg|500px|thumb|right|TJ-II Model]]

TJ-II is a flexible Heliac installed at Spain's [[Laboratorio Nacional de Fusión|National Fusion Laboratory]].
It is one of Spain's [https://www.ciencia.gob.es/Organismos-y-Centros/Infraestructuras-Cientificas-y-Tecnicas-Singulares-ICTS.html Unique Scientific and Technical Infrastructures].
It is currently operational.

== History ==

[[File:Foto_grupo_Fusion_1996.jpg|300px|thumb|left|TJ-II and the TJ-II Team in 1996]]

The flexible Heliac TJ-II was designed on the basis of calculations performed by the team of physicists and engineers of [[CIEMAT]], in collaboration with the Oak Ridge National Laboratory ([http://en.wikipedia.org/wiki/ORNL ORNL], USA) and the Institut für PlasmaPhysik at Garching ([http://en.wikipedia.org/wiki/Max-Planck-Institut_f%C3%BCr_Plasmaphysik IPP], Germany).
<ref>T.C. Hender et al, ''Studies of a flexible heliac configuration'', [https://www.osti.gov/biblio/6007697-studies-flexible-heliac-configuration Report ORNL/TM-10374 (1987) OSTI ID: 6007697]</ref>,
<ref>A. Perea et al., "Physics Issues in the Design of TJ-II, Proc. 12th European Conf. Controlled Fusion and Plasma Physics, Budapest, Hungary, 1985, [http://libero.ipp.mpg.de/libero/PDF/EPS_12_Vol1_1985.pdf ECA Vol. 9F, Part I, p. 433], European Physical Society (1985)</ref>.
The TJ-II project received preferential support from [[Euratom]] for phase I (Physics) in 1986<ref>Application for EURATOM preferential support (Phase I) - TJ-II EXPERIMENT, [https://info.fusion.ciemat.es/InternalReport/fusion_1985.pdf Technical report, Asociación EURATOM/CIEMAT, 1985]</ref> and for phase II (Engineering) in 1990<ref>Application for EURATOM preferential support (Phase II) - TJ-II EXPERIMENT, [https://info.fusion.ciemat.es/InternalReport/fusion_1989b.pdf Technical report, Asociación EURATOM/CIEMAT, 1989]</ref>. The [[TJ-II:Construction|construction of this flexible Heliac]] was carried out in parts according to its constitutive elements, which were commissioned to various European companies, although 60% of the investments reverted back to Spanish companies.

The first plasma was produced in 1997.<ref>[http://www.ciemat.es/vertices/vertices-292017/Vertices29/pdf/VERTICES29.pdf Special issue of CIEMAT's magazine ''Vertices''] commemorating 20 years of experiments (December, 2017)</ref>

== Precedents ==

TJ-II is the third magnetic confinement device in a series. In 1983, the device [[TJ-I]] was taken into operation.
The denomination of this device is due to the abbreviation of "Tokamak de la Junta de Energía Nuclear", this being the former denomination of [[CIEMAT]]. The abbreviation was maintained for successive devices for administrative reasons.

In 1994, the torsatron [[TJ-IU]] was taken into operation. This was the first magnetic confinement device entirely built in Spain. Currently, [[TJ-IU]] is located at the [http://www.ipf.uni-stuttgart.de/index_e.html University of Stuttgart] in Germany under the name of [[TJ-K]] (the 'K' stands for Kiel, its first location in Germany, before arriving in Stuttgart).

== Description ==

[[File:TJ-II_3D_perspective.jpg|300px|thumb|right|TJ-II perspective view]]

In TJ-II, the magnetic trap is obtained by means of [[TJ-II:Coil system|various sets of coils]] that completely determine the magnetic surfaces before plasma initiation. The toroidal field is created by 32 coils. The three-dimensional twist of the central axis of the [[TJ-II:Magnetic configuration|configuration]] is generated by means of two central coils: one circular and one helical. The horizontal position of the plasma is controlled by the vertical field coils. The combined action of these magnetic fields generate bean-shaped magnetic surfaces that guide the particles of the plasma so that they do not collide with the [[TJ-II:Vacuum system|vacuum vessel]] wall.

TJ-II discharges last around 0.25 s, with a repetition frequency of about 7 minutes.

They are directly [[TJ-II:Cooling system|cooled]] by water flowing trough longitudinal holes in the conductors.
All coils have a reinforced structure to avoid mechanical deformations.<ref>M. Medrano, M. Blaumoser, J. Alonso, G. Barrera, M. Pastor, C. Rubio, F. Pedrazo, and O.

The main helical field is produced by the CC, HX, and TF coils.
The vertical field coils (VF) allow positioning the magnetic axis.
The ohmic coils (OH) can generate a loop voltage of 0.1 V, intended to cancel spurious toroidal currents.
The radial coils (R) produce a trimming radial field of up to 100 G, intended to compensate stray fields.

Currents in the coil sets can be controlled in Autonomous Mode (or `A Mode') or Controlled Mode (or `C mode')<ref>A. de la Peña, L. Pacios, R. Carrasco, F. Lapayese,''A real-time current driving control system for the TJ-II coils'', [[doi:10.1016/j.fusengdes.2008.12.010|Fusion Engineering and Design '''84''', Issues 2–6 (2009) 676-680]]</ref>.

Bolometry has been used to classify radiation profiles into two categories: 'bell' and 'dome', related to impurity concentration inside the plasma. 'Bell'-type profiles are more robust against radiative collapse<ref>F.L.

== Multichannel Soft X-Ray system ==

[[File:TJ-II_Soft-X_array.jpg|400px|thumb|right|TJ-II Soft X-Ray camera array]]

The [[TJ-II]] multichannel soft X-ray system consists of 5 cameras with 16 channels each,
allowing tomographic reconstruction of the plasma emissions (using the [[EBITA]] code).
<ref>F. Medina et al, ''X-ray diagnostic systems for the TJ–II flexible heliac'', [[doi:10.1063/1.1149517|Rev. Sci. Instrum. '''70''' (1999) 642]]</ref>

The system is located in [[TJ-II:Sectors|sector]] A2, at φ = 104.5°.
The signals are stored in the [[TJ-II:Shot database|TJ-II database]] with the names 'RXxyy', where 'x' = 1,...,5 (corresponding to the five arrays) and 'yy' = 01,...,16 (corresponding to the 16 channels).

EU-US Transport Task Force Meeting

2026-09-04T17:13:27Z

Admin: /* List of conferences */

The joint EU-US TTF meeting or workshop is held alternately in the USA and in Europe.
Its focus is on transport in magnetized plasmas, covering theory, experiment, and modeling aspects.

In the period 2003-2005, the logical enumeration of the workshop was disrupted.

EU-US Transport Task Force Meeting

2026-09-04T17:03:50Z

Admin:

The joint EU-US TTF meeting or workshop is held alternately in the USA and in Europe.
Its focus is on transport in magnetized plasmas, covering theory, experiment, and modeling aspects.

In the period 2003-2005, the logical enumeration of the workshop was disrupted.

[[File:CIEMAT.jpg|400px|thumb|right|CIEMAT logo]]
The Centro para Investigaciones Energéticas, Medioambientales y Tecnológicas (Centre for Energy, Environment and Technology Research, CIEMAT), an Organism of the Spanish Ministry of Science and Innovation, is a Public Research Agency that is mainly focused on the energy and the environment, but also conducts studies into many advanced technologies and in various areas of fundamental research. Its staff numbers upward from 1200.

== History ==

The CIEMAT is the successor of the Junta de Energía Nuclear (JEN), founded in 1951 by a Decree (dated October 22, 1951) with the purpose of studying the pacific application of nuclear energy and ionizing radiation.

In 1986, the organization was renamed CIEMAT, and its scope was enhanced to include other forms of alternative energy, to study the environmental impact of energy generation, and to develop associated technologies.

== Goals ==

CIEMAT focuses on research and technological development projects, serving as a reference for the technical representation of Spain in international forums, and advising government on matters within its field of competence. Its main goals are:
* To develop alternative energy sources
* To improve energy efficiency and optimize energy generating systems
* To improve the efficiency and reduce the environmental impact of fossil fuels
* To improve the safety of energy generation by nuclear fission
* To study the feasibility of [[Nuclear fusion|nuclear fusion]] as a future energy option
* To improve the competitiveness of renewable energy sources in the energy market
* To develop solutions for improving the environmental quality

== Research centres ==

CIEMAT possesses three research centres:
* The main establishment is in Madrid (Moncloa), and that is where the [[Laboratorio Nacional de Fusión]] is located.
* The Solar Platform in Almería <ref>[http://www.psa.es/webeng/index.php The Solar Platform]</ref> - the largest solar energy plant in Europe, located in the Tabernas Desert.
* The Centre for Renewable Energy Development in Soria. <ref>[http://www.ciemat.es/CEDERportal/portal.do The Centre for Renewable Energy Development]</ref>

Admin:

SIESTA is an ideal [[MHD equilibrium|MHD 3D-equilibrium]] solver, capable of dealing with [[Magnetic island|magnetic islands]] and stochastic regions in a fast, accurate and scalable manner.
<ref>S. P. Hirshman, R. Sanchez, and C. R. Cook, ''SIESTA: A scalable iterative equilibrium solver for toroidal applications'', [[doi:10.1063/1.3597155|Phys. Plasmas 18, 062504 (2011)]]</ref>

The SIESTA code will complement other existent 3D MHD island solvers and is particularly suited for applications that require not only accuracy but speed of evaluation as well, such as experimental 3D equilibrium reconstruction or stellarator design. SIESTA will also be useful to calculate MHD equilibria at very high spatial resolutions, such as those that might be required for the investigation of NTMs at [[ITER]]-relevant temperature and resistivity conditions. SIESTA is based on a preconditioned, iterative algorithm that takes advantage of a pre-existent [[VMEC]] solution to provide both a background coordinate system that guarantees a compact representation as well as a good initial guess for the iterative procedure.
