Abstract :
Gyrotrons are widely used in electron-cyclotron-plasma heating of fusion installations. Modern and future installations require microwave sources with power of at least 1 MW. There are two main directions in the development of megawatt gyrotrons at GYCOM. The first line is an enhancement of parameters for conventional gyrotrons. The main efforts are applied now to implementing of CVD diamond windows into the gyrotrons and providing gyrotron operation in CW (or very long pulses of tens seconds) regime.
