50kW CW Highly-Efficient Multi-Beam Klystron at 952 MHz for a Future Electron-Ion Collider

Abstract

Initial results are presented for the development of a continuous-wave highly-efficient radio-frequency (RF) source for applications at Thomas Jefferson National Accelerator Facility (TJNAF). The project goal is to design and demonstrate a compact CW multi-beam klystron amplifier (MBK) with a high efficiency (> 80%) capable of supplying 50 kW of RF power at 952.6 MHz. RF sources with these specifications are sought for the high-level RF system for ion acceleration in the Medium Energy Electron Ion Collider that is being developed at TJNAF.
