飞秒电子束装置的初步实验结果
Preliminary results of a femto-second electron bunch facility
摘要
上海应用物理研究所建造并调试了一台飞秒电子束装置.这台装置主要由一把S波段热阴极微波电子枪、一台alpha磁铁和一根SLAC型加速管组成.这台装置可以产生能量为 20～30 MeV,峰值电流为100 A,微束团长度为250 fs的电子束.这篇文章报道了这台装置的调试和电子束团参数的测量.
Abstract
A femto-second electron bunch facility has been constructed and commissioned at the Shanghai Institute of Applied Physics(SINAP).The linac of this facility consists of an S-band thermionic cathode RF-gun,an alpha magnet and a SLAC-type accelerating tube to generate a beam,then compress the micro-bunches,and finally accelerate the beam to 20～30 MeV.Preliminary experimental result shows that the length of the micro-bunches is about 250 fs.The measured beam parameters of this facility are presented in this paper.
