Space-Charge Limiting Currents in a Drift Tube of Finite Length.

Abstract

The equation governing the steady state potential distribution created by a cold unneutralized annular relativistic electron beam propagating axially within a finite length drift tube with grounded anode foil, collector plate, and walls and immersed in an axially directed infinite magnetic guide field is solved numerically using the method of finite elements. These numerical results are used to check the accuracy of available analytical approximations to the limiting current.
