Design, fabrication, and test of an X-Band multiple beam klystron

Fabrication was completed on an X-Band multiple beam klystron (MBK) designed to produce 50 MW of RF power in microsecond pulses. The klystron incorporates a confined flow, multiple beam gun where the cathodes are located relatively far from the device axis. This required unique focusing structures to maintain beam quality. The MBK will be tested at Brookhaven National Laboratories.
