Abstract :
The development of a 2 MW, CW, 170 GHz coaxial cavity gyrotron at Forschungszentrum Karlsruhe (FZK) is in progress in cooperation with several European research institutions. The gyrotron is foreseen as a source for heating, current drive and plasma stabilization in the International Thermonuclear Experimental Reactor (ITER). The design of critical components, especially the electron gun, cavity and quasi-optical RF output system are verified at FZK in tests with a short pulse gyrotron.
