Development of the Multi-Beam Transmission Line for DTT ECRH system
The DTT tokamak, whose construction is starting in Frascati (Italy), will be equipped with an ECRH system of 16 MW for the first operation phase and with a total of 32 gyrotrons (170 GHz, ≥ 1 MW, 100 s), organized in 4 clusters of 8 units each in the final design stage.To transmit this large number of power beams from the gyrotron hall to the tor
