本文通过实验验证CR-39临界角是其不能探测到100 keV以下质子能谱的原因.并据此改进探测方案,利用CR-39和Thomson谱仪测得超强激光与5μm厚A1靶作用产生的100 keV以下的质子能谱.探讨了利用单粒子模拟法处理Thomson谱仪的数据,该方法规避了谱仪中磁场边缘场对测量的影响,提高了谱仪测量精度.%It was proved by experiments that CR-39 solid track detector can't detect protons below 100 keV because of its critical angle in the paper. Hereby, the detection arrangement was improved. The proton energy spectrum below 100 keV was measured by CR-39 solid track detector and Thomson spectrometer in the experiment of laser interaction with 5 μm Al foil. Single particle simulation was used to process data from the magnetic spectrometer, which can avoid the error from fringe magnetic field in spectrometer and improve the precision.
