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 2<sup>nd</sup> harmonic, with X-mode polarisation. | 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 2<sup>nd</sup> harmonic, with X-mode polarisation. | ||
