实用光电倍增管测量多泡声致发光强度

摘要

Based on the experiment of phosphoric acid liquid sonoluminescence ,the function and application of CR131 type photomultiplier tube were introduced .The internal and external circuit connection of CC 171 ,adjust-mend methods ,the fault of PM T and its settlement are also discussed .Finally ,some suggestions are given for further research .%CC171作为光电倍增管专用供电电源，正确使用及外部电路调整使它处于最佳的工作状态直接影响CR131的测量精度。本文以磷酸液声致发光实验为基础，介绍了CR131型光电倍增管在实验中的作用和应用，CC171高压管座内外电路连接方式及调整方法以及PM T简单故障辨别与处理。根据实验过程中遇到的一些实际问题提出了改善建议。
