In the torsatron TJ-IU, a single coil generates the helicoidal magnetic field (l=1). The number of turns of the coil around the vacuum chamber is m=6. The vertical field is generated by a set of vertical field coils.
| Parameter | Value | Unit |
|---|---|---|
| Major radius, R0: | 0.60 | m |
| Mean plasma radius, a: | 0.10 | m |
| Minor coil radius, Rc: | 0.24 | m |
| Number of periods, m: | 6 | |
| Rotational transform at the axis, ι0: | 0.30 | |
| Magnetic shear: | almost zero | |
| Magnetic well depth: | 6.9 | % |
| Magnetic ripple at the axis: | 7.6 | % |
| Helical axis elongation: | 0.025 | m |
| Toroidal field, BT, at φ=30 degrees: | 0.5 | T |
| 2nd harmonic Electron Cyclotron Heating, 28 - 37.5 GHz: | 200 | kW |
The device was entirely built in Spain and taken into operation in 1994. In 1999, the device was sent to the University of Kiel, Germany, under a permanent loan agreement, and renamed TJ-K. Currently, TJ-K is located at the University of Stuttgart in Germany.
