Abstract

To control different types of magnetohydrodynamic (MHD) instabilities in ITER, various amplitude modulation scenarios for the gyrotrons of the Electron Cyclotron (EC) system are required. This work focuses on the impact of different modulation scenarios on the power loading on the collector wall of a 2 MW gyrotron, which has been originally proposed as the EU gyrotron for ITER. In addition, first investigations of the transient thermal behavior of the collector structure have been performed.
