	Funding: Department of Energy Office of Science SBIR Grant No. DE-SC0007591 Calabazas Creek Research, Inc. is developing a pulsed 5 MW S-band Periodic Permanent Magnet (PPM) klystron capable of replacing the solenoid focused 5 MW Klystron currently in production for medical accelerators. The most important improvement is the large reduction in space required for the current solenoid - solenoid power supply -klystron. The PPM klystron will require a substantially reduced volume while maintaining the current operating parameters. The initial development effort will be focused on determining the maximum electron beam perveance allowable with PPM focusing. The determination of this parameter will dictate the electron beam-interaction circuit and the required electron gun - collector design. Detailed parameters, simulation and fabrication results will be presented.
