摘要: 介绍了用磁分析器和图象处理系统测量强流脉冲电子束能量及能散度的原理和实验研究工作,给出了西南流体物理研究所直线感应加速器的测量结果,电子束最可几能量为3.47 MeV,最大能量为3.51 MeV,能散度为1.0％,并给出了电子束的能谱分布曲线。磁分析器偏转半径为150mm,偏转角度为90°。Abstract: This paper describes the principle of the energy spectrum measurement system including the magnetic analyzer and image processing unit. The experimental results of the 3.3MeV LIA IPEB are presented. The most possible energy is 3.47MeV, and the maximum 3.51MeV. The energy spread is 1%. The energy spectrum distribution of the IPEB is given. Discussion on the experimental results and the measurement of IPEB energy spectrum are made in the paper. The main effect factors on the energy and its spread of the LIA IPEB are also analyzed and calculated numerically.
