Abstract

By using an incident electron beam with the high current and high energy， the guiding effect of the bended macroscopic quartz tube for the electron beam has been investigated. The angular distributions of outgoing electrons depending on the current and energy of incident electrons were measured. The dependences of electron transmitted fraction on energy and current of incident electrons are also shown. As the incident electron energy increasing， the electron transmitted fraction increases， but it decreases while the incident electron current increasing. The results have been compared with the present data. This work presents， the process of guiding electrons is essentially different from that of guiding highly charged ions， the guiding electron beam was caused by both elastic and inelastic collisions between electrons and inner walls of quartz tube， rather than selforganized charging effect on the surface of inner wall of quartz tube.
