(fabricated by the [http://antenas.unavarra.es/ ''Antenna Group of the Public University of Navarra, Spain'']) which emits a microwave beam with a gaussian electric field distribution. The beam is reflected by a steerable ellipsoidal mirror to the plasma. The mirror serves for two purposes: 1) focus the microwave beam (obtaining plane wavefronts) to the region where backscattering takes place and 2) change the angle of incidence between beam and plasma, giving the possibility to select the turbulence scale to be measured.<br />
<br />
Different scenarios can be realized: Positive or negative incidence angles of the incident beam or perpendicular incidence, which is equivalent to a conventional reflectometer system. The [[Effective_plasma_radius|radial]] position of scattering and the probed perpendicular wavenumber are calculated after the discharge using the 3D ray/beam-tracing code [[TRUBA]].<br />

<div>The best and most complete theory of transport in magnetically confined systems is the [[Neoclassical transport|Neoclassical]] theory.<br />
However, it is found that transport often exceeds Neoclassical expectations by an order of magnitude or more (also see [[Non-diffusive transport]]).<br />
<ref>[http://dx.doi.org/10.1063/1.859358 A.J.Wootton et al, ''Fluctuations and anomalous transport in tokamaks'', Phys. Fluids B ''2'' (1990) 2879]</ref><br />
The difference between actual transport and the Neoclassical expectation is called "[[:Wiktionary:anomaly|anomalous]]" transport.<br />
It is generally assumed that the anomalous component of transport is generated by turbulence driven by micro-instabilities.<br />

<br />
== How important is turbulence? ==<br />
<br />
In spite of lengthy studies into the subject, it is still controversial how important turbulent transport really is. <br />
In part, this may be because turbulent transport gives a variable contribution to transport (depending on local and global parameters), whereas Neoclassical transport is always present.<br />
And in part, because no complete theory for anomalous transport is available.<br />
<ref>[http://dx.doi.org/10.1088/0741-3335/36/5/002 J.W. Conner and H.R. Wilson, ''Survey of theories of anomalous transport'', Plasma Phys. Control. Fusion '''36''' (1994) 719-795]</ref><br />
<br />
=== Arguments in favour ===<br />
<br />
An important argument suggesting that anomalous transport is important to the degree that it often dominates the total transport is the [[Scaling law|scaling]] of transport with heating power and machine size. <br />
<ref>[http://dx.doi.org/10.1109/27.650902 B.A. Carreras, ''Progress in anomalous transport research in toroidal magnetic confinement devices'', IEEE Trans. Plasma Science '''25''', 1281 (1997)]</ref><br />
The phenomenon of [[Scaling law|power degradation]], universally observed in all devices, is an indication that standard transport theories are inadequate to explain all transport, since these would not predict power degradation.<br />
Following Freidberg,<br />
<ref name="Freidberg" /><br />
the cited [[Scaling law|scaling laws]] can be rewritten in terms of the temperature dependence (eliminating the heating power dependence). <br />
Then, classical and neoclassical estimates would predict that the confinement increases with ''T'' (namely: ''&tau;<sub>E</sub>'' &prop; ''T<sup>0.5</sup>'', associated with collisionality).<br />
However, the experimental scalings give a ''decrease'' with ''T''<br />
(namely: ''&tau;<sub>E</sub>'' &prop; ''T<sup>&alpha;</sup>'' with '' &alpha;'' &lt; -1).<br />
This unexpected behaviour is explained from increased turbulence levels (and enhanced transport) at higher values of (the gradients of) ''T''.<br />
<br />
[[Profile consistency]] indicates that [[Self-Organised Criticality|self-organisation]] plays an important role in transport, and this can only be the case when instabilities or turbulence are able to regulate the profiles, i.e., when they carry an important fraction of transport.<br />
<br />
The suppression of turbulence is possible, either actively (by imposing an external radial electric field), or spontaneously ([[H-mode]]s, [[Internal Transport Barrier]]s). As a consequence, transport is reduced significantly (to Neoclassical levels). This is a clear indication that turbulence is responsible for the main fraction of anomalous transport.<br />
<br />
=== Arguments against ===<br />
<br />
It has been argued that turbulence cannot be responsible for a significant fraction of the anomalous component of transport, since that would lead to high resistivity (due to collisions), which contradicts experimental observation.<br />
<ref>L.C. Woods, ''Theory of tokamak transport: new aspects for nuclear fusion reactor design'', John Wiley and Sons (2006) ISBN 3527406255</ref><br />
However, this argument fails to note that transport events may be collective (e.g., via ''streamers''), which do not require an enhanced collisionality.<br />
<br />
== Can anomalous transport be modelled? ==<br />
<br />
There are several answers to this question. Since all equations describing the motion of charged particles in fields are known, including the effects of collisions, detailed numerical (gyrokinetic) simulations are possible.<br />
<ref>[http://link.aps.org/doi/10.1103/PhysRevLett.77.71 A.M. Dimits et al, ''Scalings of Ion-Temperature-Gradient-Driven Anomalous Transport in Tokamaks'', Phys. Rev. Lett. '''77''' (1996) 71 - 74]</ref><br />
However, due to the enormous disparity between the minimum and maximum scales involved (gyration times vs. transport times, and the gyroradius vs. the machine size), this is a major challenge. <br />
<br />
An alternative approach is to model the net effect of turbulence without simulating the fine detail.<br />
In doing so, it is not sufficient to introduce a simple additional "turbulent diffusivity", as this cannot possibly reproduce the observed global transport scaling behaviour.<br />
It is probably necessary to use a [[Non-diffusive transport|non-diffusive]] description. <br />
<ref>[http://dx.doi.org/10.1016/S0370-1573(02)00331-9 G. M. Zaslavsky, ''Chaos, fractional kinetics, and anomalous transport'', Physics Reports '''371''', Issue 6 (2002) 461-580]</ref><br />
<br />
== Can anomalous transport be controlled? ==<br />
<br />
Yes. <br />
The impression is that anomalous transport is more difficult to control in tokamaks than in stellarators. However, limited control in tokamaks is possible by making use of edge transport barriers (cf. [[H-mode]]) and [[Internal Transport Barrier]]s (ITBs). This reduces transport to Neoclassical levels, at least transiently.<br />
<br />
Particularly in optimised stellarators (W7-AS), transport can be close to Neoclassical levels.<br />

TJ-II is a flexible Heliac installed at Spain's [[Laboratorio Nacional de Fusión|National Fusion Laboratory]]. <br />
It is one of Spain's [http://univ.micinn.fecyt.es/ciencia/jsp/plantilla.jsp?area=instalaciones&id=21 Large Scientific Installations].<br />
It is currently operational.<br />
<br />
== History ==<br />
<br />
[[File:Foto_grupo_Fusion_1996.jpg|300px|thumb|left|TJ-II and the TJ-II Team in 1996]]<br />
<br />
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). The TJ-II project received preferential support from [[Euratom]] for phase I (Physics) in 1986 and for phase II (Engineering) in 1990. The [http://dx.doi.org/10.1109/FUSION.1997.687032 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.<br />
<br />
The first plasma was produced in 1999.<br />
<br />
== Precedents ==<br />
<br />
TJ-II is the third magnetic confinement device in a series. In 1983, the device [[TJ-I]] was taken into operation.<br />
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.<br />
<br />
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.<br />
<br />
== Description ==<br />
<br />
[[File:TJ-II_3D_perspective.jpg|300px|thumb|right|TJ-II perspective view]]<br />
<br />
In TJ-II, the magnetic trap is obtained by means of 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 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 vacuum vessel wall. <br />
<br />
TJ-II discharges last around 0.25 s, with a repetition frequency of about 7 minutes.<br />
<br />
== Goals and Research ==<br />
<br />
The objective of the experimental program of TJ-II is to investigate the physics of a device with a helical magnetic axis having a great flexibility in its magnetic configuration, and to contribute to the international effort regarding the study of magnetic confinement devices for fusion. <br />
<br />

<br />
An extensive set of systems is available to perform [[TJ-II:Plasma Wall Interaction|plasma wall conditioning]].<br />
<br />
Two movable [[TJ-II:Limiter|limiters]] can be used to limit the plasma.<br />
<br />
A [[TJ-II:Biasing probe|biasing probe]] can be used to apply a bias potential at the edge.<br />

, measuring plasma density fluctuation velocities and their wave number spectra. The system is able to measure in a radial range of about &rho; = 0.6 - 0.9 (&rho; = r/a is the [[effective plasma radius]]) and the perpendicular wavenumber can be selected between 3 and 15 cm<sup>-1</sup>.<br />
<br />
The system consists of a circular choked-corrugated antenna<br />

(fabricated by the ''Antenna Group of the Public University of Navarra, Spain'') which emits a microwave beam with a gaussian electric field distribution. The beam is reflected by a steerable ellipsoidal mirror to the plasma. The mirror serves for two purposes: 1) focus the microwave beam to the region where backscattering takes place and 2) change the angle of incidence between beam and plasma, giving the possibility to select the turbulence scale to be measured.<br />

(fabricated by the ''Antenna Group of the Public University of Navarra, Spain'') which emits a microwave beam with a gaussian electric field distribution. The beam is reflected by a steerable ellipsoidal mirror to the plasma. The mirror serves for two purposes: 1) focus the microwave beam to the region where backscattering takes place and 2) change the angle of incidence between beam and plasma, giving the possibility to select the turbulence scale to be measured.<br />
