New page

The magnetic configurations of the low shear stellarator [[TJ-II]] in vacuum are specified by a label consisting of 3 numbers: X_Y_Z.
These numbers represent the currents flowing in the [[TJ-II:Coil system|external coils]].
* X is the current in the helical coil (HX, in kA) times 10
* Y is the current in the circular coil (CC, in kA) times 10
* Z is the current in the vertical field coil (VF, in kA) times 10
The current in the toroidal field coils (TF) is not specified, as it is defined implicitly by requiring that the magnetic field <math>|B|</math> equals 0.95 T at the magnetic axis in the relevant poloidal cross sections
(where [[TJ-II:Electron Cyclotron Resonant Heating|ECRH]] is injected) in order to ensure central power deposition.

A wide range of configurations is available. The following table lists a number of them.

== Flexibility ==

[[File:Flexibility_TJ-II.png|thumb|300px|right|Flexibility diagram]]
The magnetic configurations of TJ-II offer ample flexibility in terms of rotational transform, plasma volume, and magnetic well, among others.
The diagram shows the variation in the rotational transform as a function of <math>I_{CC}</math> and <math>I_{HX}</math>.
The plasma size rav increases with <math>I_{CC}+I_{HX}</math>, so that reasonably-sized plasmas are limited to the upper right triangle of this diagram.

Only some of the available range of configurations has been explored experimentally, as in the so-called well scan experiments<ref>A.M. de Aguilera, F. Castejón, E. Ascasíbar, E. Blanco, E. de la Cal, C. Hidalgo, B. Liu, A. López-
Fraguas, F. Medina, M.A. Ochando, I. Pastor, M.A. Pedrosa, B. van Milligen, and the TJ-II Team. ''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>.
