Abstract :
A 2 MW, CW, 170 GHz coaxial cavity gyrotron for electron cyclotron heating and current drive in the International Thermonuclear Experimental Reactor (ITER) is under development in cooperation between European Research institutions. The design of critical components, especially the electron gun, cavity and quasi-optical (q.o.) RF-output system has been studied on a short pulse coaxial gyrotron (pre-prototype) at the Forschungszentrum Karlsruhe (FZK). Recent results of the experimental investigations will be presented and discussed.
