Gyrotron body power supply, validation of design with test results

A 170 GHz, 2 MW, steady state gyrotron is being developed in a collaboration between European research associations and industries to be used for the electron cyclotron resonance heating (ECRH) system of ITER, the next step in nuclear fusion research. The gyrotron is presently in the prototype state. For the test facility dedicated to the testing of this gyrotron, new power supplies need to be procured. A feasibility study was performed aimed at using new designs based on present day techniques and at performing and constructing a prototype for further testing and evaluation. The prototype BPS (body power supply) which is connected to the body of the gyrotron is now in an advanced stage of construction and the first test results are in close agreement with the design objectives of the feasibility study.
