测量电子束流的小型法拉第筒
A COMPACT FARADAY CUP FOR THE MEASUREMENT OF ELECTRON BEAM
-
摘要: 介绍一种测量束流强度不大于50kA,能量不超过0.8MeV的小型法拉第筒。经标定,此法拉第筒上升前沿小于6ns。已用于契伦柯夫自由电子激光的传输束流测量。Abstract: A compact structure, easily using Faraday cup was designed and tested for measuring electron beam which is less than 50kA with energy less than 0.8MeV. The method of calibrating was described and the risetime was found less than 6ns. The cup has been used to measure transmitted beam currents in the Cerenkov free electron laser experiment.
