In the TJ-II stellarator, the plasmas are created and heated by two 53.2 GHz gyrotrons, each of them delivering up to 300 kW in the 2nd harmonic, with X-mode polarisation. The power is transmitted to the plasma by two quasi-optical transmission lines (QTL1 and QTL2). [1] The power is delivered to the sector B3 (for QTL1) and A6 (for QTL2). The last mirror of each line is a steerable mirror located inside the vacuum vessel, which allows for perpendicular and oblique injection. [2] [3] [4] [5] The gyrotrons can be modulated.
