CCR’s Periodic Permanent Magnet (PPM) focused klystron completed bakeout today. The tube is currently being prepared for high power testing at Communications & Power Industries, LLC. The klystron is being developed for a new generation of cancer therapy machines (CLINACs) produced by Varian Medical Systems, Inc. The PPM-focused klystron would replace traditional solenoid-focused klystrons, reducing the size and weight of the system.
The klystron is designed to produce 5.5 MW RF pulses at 2.856 GHz at approximately 50% efficiency. This development is funded by the U.S. Department of Energy through grant number DE-SC0007591.
