Gyrotrons as High-Frequency Drivers for Undulators and High-Gradient Accelerators

Gyrotrons are used as high-power sources of coherent radiation operating in pulsed and CW regimes in many scientific and technological fields. In this paper, we discuss two of their numerous applications. The first one is in gyrotron-powered electromagnetic wigglers and undulators. The second one is for driving high-gradient accelerating structures in compact particle accelerators. The comparison, between the requirements imposed by these two concepts on the radiation sources on one hand and ...

In-vessel piezoelectric actuation system for DTT ECRH launchers: Conceptual design

The Electron Cyclotron Resonance Heating (ECRH) system of Divertor Tokamak Test (DTT) facility will feature up to 35.2 MW installed power. At the time of its completion, it will be the most powerful ECRH system ever realized. In full power configuration, 4 sectors of the tokamak will be equipped with equatorial and upper antennas with respectively 6 and 2 launchers each, for a total of 32 launchers, fed by 16 1-MW, 170-GHz gyrotrons and 16 1.2-MW, 170-GHz gyrotrons. The last mirror of each EC...
