Abstract

To control different types of magnetohydrodynamic instabilities in the fusion experiment ITER, various amplitude modulation scenarios for the gyrotrons of the electron cyclotron system are required. This paper focuses on the impact of different modulation scenarios on the power loading on the collector wall of the 2-MW EU gyrotron. In addition, first investigations of the transient thermal behavior of the collector structure are performed.
