The 10 MW EPSM modulator and other key components for the KIT gyrotron test facility FULGOR

摘要

In recent years Electron Cyclotron Resonance Heating (ECRH) has become the prime heating system on most fusion machines, due to the availability of gyro trons and transmission systems as reliable high power microwave sources. The Institute of Pulsed Power and Microwave Heating (IHM) at the Karlsruhe Institute of Technology (KIT) is at the center of European efforts in developing such gyrotrons, in collaboration with European industry and other research institutions. Two years ago, KIT has started the construction of a new gyrotron test facility FULGOR (Fusion Long Pulse Laboratory), which should satisfy the demands gyrotron testing poses over the next 2-3 decades. The paper describes the capabilities of FULGOR and the progress made in its construction. (C) 2017 Published by Elsevier B.V.
