Abstract

During last year several new gyrotrons were designed and tested by Russian gyrotron team. Main efforts were spent for elaboration of 170 GHz/1 MW/50%/CW gyrotron for ITER project and multi-frequency gyrotrons. The paper presents new results in development of gyrotrons for ITER. The industrial production prototype of the ITER gyrotron was tested at power 1.02 MW in 100 second pulses and at power 0.85 MW in 200 second pulses. The pulse energy was limited by the test stand which is now under modification. Simultaneously a short pulse gyrotron mock-up with an increased size cavity was tested at power 1.5-2 MW aiming development of ITER gyrotron with the enhanced power.
