Abstract

This paper describes the design and experimentation of electrostatic focusing of electron beam using a demountable vacuum measurement setup. Initially a focusing setup is designed for focusing a single on-axis low perveance beam. The design was carried out using an in house developed 2.5 D finite difference electron optics code PIERCE and CST Particle Studio. This focusing scheme is being extended for multiple beams of same perveance for a compact klystron device.
