Design and R&D for an ECRH power supply and power modulation system on jet

An electron–cyclotron resonance heating (ECRH) system has been designed for Joint European Torus (JET) in the framework of the JET-Enhanced Performance project (JET-EP) under the European Fusion Development Agreement (EFDA). Due to financial constraints it has recently been decided not to implement this project. Nevertheless, the design work conducted from April 2000 to January 2002 shows a number of features, which can be relevant in preparation of future ECRH systems such as the International Thermonuclear Experimental Reactor (ITER) one. The system was foreseen to comprise six gyrotrons, 1 MW each, in order to deliver 5 MW of mm-wave power into the tokamak plasma (Verhoeven et al. The ECRH system for JET).
