SiC MOSFETs Bipolar Marx generator Prototype for the Super MuSR Beamline Electrostatic Chopper at ISIS

This work presents the results of a demonstration solid-state bipolar ± 15kV Marx generator prototype, based on SiC MOSFETs, developed as a feasibility study of this technology for the chopper that will be installed in the Super MuSR beamline, proposed to upgrade the existing muon spin spectrometer at ISIS Neutron and Muon Source at the STFC Rutherford Appleton Laboratory, UK. The design of the assembled 20 stage bipolar solid-state Marx, using 1000V/90A off-the-shelf SIC MOSFETs, producing about ± 15kV, 150 A into the 51 pF load are described and the concept is evaluated.
