In the TJ-II stellarator, the plasmas are created and heated by two 53.2 GHz gyrotrons, each of them delivering 300 kW. The power is transmitted to the plasma by two quasi-optical transmission lines (QTL1 and QTL2). 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. [1] [2] The gyrotron frequency is f = 53.2 GHz, tuned to the 2nd harmonic, X-mode polarisation. The total power that can be delivered to the plasma is PECRH ≤ 600 kW. The gyrotrons can be modulated.
