X-Band Sheet Beam Klystron (XSBK)

Abstract

The sheet beam klystron (SBK) is characterized by a large drift tube, which allows the use of high beam current at a low voltage, resulting in low beam current density, high efficiency and the possibility of PPM focusing. CPI has designed, manufactured and is currently testing an X-Band SBK capable of 5 MW peak, 20 kW average output power. This paper discusses the general design, manufacturing and performance to date of CPI's X-Band SBK.
