Development of a 50 MW PPM

Calabazas Creek Research, Inc. is developing a 50 MW Periodic Permanent Magnet (PPM) Focused High Efficiency klystron capable of driving advanced superconducting linacs. The development addresses the high RF power needs for the LANL MaRIE proton linear accelerator. We will present tabulated and graphical data showing in detail the performance of this pulsed klystron. We will compare results from our in-house klystron large signal code, KLSC and our leased large signal code, TESLA for a 7 cavity circuit. We will also present results for a single output cavity and for a multiple cavity extended interaction circuit (EIC).
