1300 MHz PPM Focused Klystron for Project X

Project X at the Fermi National Accelerator Laboratory requires a 1300 MHz, 0.5 MW long pulse klystron for driving accelerator cavities. Calabazas Creek Research, Inc. (CCR) is proposing to develop a 0.5 MW 1 MW focused klystron that incorporates a unique time proven Periodic Permanent Magnet (PPM) focusing structure in lieu of the solenoid focusing. The final design is expected to have an overall efficiency & gt;60% and will eliminate the need for expensive focusing solenoid-DC power supply combinations and substantial water cooling. Incorporation of this PPM focused klystron will increase the efficiency of the accelerator. Commercial Applications and Other Benefits: This PPM focused klystrons simple geometry minimizes fabrication and power supply costs over other klystrons with conventional solenoidal focusing. Klystrons are used in many accelerators for research and medical applications, and for radar and communications in industry and national defense applications. In all of these applications, a PPM focused klystron is expected to offer a significant cost advantage.
