Valhalla is a klystron modulator utilizing solid-state IGBT switches based off a patented parallel Marx generator topology with built in droop compensation. The small footprint allows the system to be designed into rotating gantries and several novel features exist that greatly reduce the MTTR compared to competitive systems.
