The TJ-II coil system is listed in the table below. All coils are directly cooled by water flowing trough longitudinal holes in the conductors. All coils have a reinforced structure to avoid mechanical deformations.
| Coil | Number | Size (m) | Turns |
|---|---|---|---|
| Circular (CC) | 1 | R = 1.5 | 24 |
| Helical (HX) | 1 | R = 1.5 swing = 0.07 |
24 |
| Toroidal (TF) | 28 | r = 0.425 | 8 |
| Toroidal (TF) | 4 | r = 0.475 | 9 |
| Vertical (VF) | 2 | R = 2.25 | 16 |
| Compensation (OH) | 2 | R = 0.78 | 20 |
| Compensation (OH) | 2 | R = 2.29 | 1 |
| Radial (R) | 2 | R = 0.74 | 7 |
| Radial (R) | 2 | R = 2.24 | 5 |
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.
