快电子发散角的实验测量
Experimental measure of the divergence angle of fast electrons from a Cu target irradiated by intense femtosecond laser pulses
摘要
Abstract
The divergence angle of fast electrons produced in the interaction of femtosecond laser with Cu target has been measured by using an angular distribution instrument adding the LiF thermoluminescent dosimeters.The results show that the divergence angle of fast electrons is highly related with the incidence angle of laser pulses. The divergence angle of fast electrons gets small when increasing the incidence angle of laser pulses.By adding a prepulse to generate preplasma, the divergence angle of fast electrons is lesser than that without a prepulse. The result is helpful for getting a fast electron beam with small divergence angle.关键词
