The Effects of Transverse Motion on Electron Back Bombardment in Standing Wave Linear Accelerators,
Abstract
Electron back bombardment in standing wave linear accelerators LINACS is an undesirable phenomenon which can cause the electron gun cathode to overheat and destroy electron optics. It is related not only to longitudinal motion factors, but also to transverse motion factors. This paper analyzes the effects of transverse motion on electron back bombardment and point out that owing to transverse motion, only part of the backward motion electrons can back bombard the electron gun cathode surface. The authors provide methods for calculating back bombardment beam envelopes, back bombardment ratios, back bombardment currents, and back bombardment power.
