The [[TJ-II]] coil system is listed in the table below (in [[Toroidal coordinates|cylindrical coordinates]]). | The [[TJ-II]] coil system is listed in the table below (in [[Toroidal coordinates|cylindrical coordinates]]). | ||
All coils are directly [[TJ-II:Cooling system|cooled]] by water flowing trough longitudinal holes in the conductors. | All coils are circular, except the helical coil. | ||

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. Heusmann, ''Strength considerations on the magnetic field coils of the Spanish Stellarator TJ-II'', [[doi:10.1109/FUSION.1993.518529| Fusion Engineering, 15th IEEE/NPSS Symposium (1993)]]</ref> | All coils have a reinforced structure to avoid mechanical deformations.<ref>M.

The ohmic coils (OH) can generate a loop voltage of 0.1 V, intended to cancel spurious toroidal currents. | 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. | 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.
