Abstract
An intense electron beam travelling axially through a superconducting tube is studied. We show numerically that it is necessary to compensate the space-charge effect of the electron beam nearly completely in order to focus the beam by means of the superconductor tube. The tube functions as a lens not only for electrons injected parallel to the tube axis but also for electrons having a small initial radial velocity component. Additionally, it is suggested that the simple straight superconducting tube may function as a wiggler for free-electron lasers.This publication has 4 references indexed in Scilit:
