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. [1] The power is transmitted to the plasma by two quasi-optical transmission lines (QTL1 and QTL2). [2] 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. [3] [4] [5] [6] The gyrotrons can be modulated for perturbative transport experiments [7] and can be used to drive current. [8]
