The TJ-K device is a torsatron with a single helical coil (l=1, m=6).
History
TJ-K was originally named TJ-IU, and was constructed at CIEMAT in Madrid, Spain. TJ-IU was taken into operation in 1994, and was operated at relatively high magnetic field (0.5 T) and heating power (200 kW of ECRH heating), and corresponding relatively high values of the plasma parameters (electron density: 5 × 1018 m-3).
In 1999, TJ-K was transferred to Kiel, Germany, and in 2005 to the IPF institute in Stuttgart, Germany. In its reincarnation as TJ-K, the device is operated at low magnetic field (about 0.07 T) and heating (1-6 kW of ECRH heating), and corresponding relatively low values of the plasma parameters (electron density: 5 × 1017 m-3; electron temperature: 10 eV; ion temperature: 1 eV).
