摘要
研制计数管监测器,通过监测55Fe 5.9keV X射线光电峰,实时监测BESⅢMUON探测器的气体配比。经过系列实验研究了计数管的各种性能,明确其工作模式为有限正比模式;选取最佳工作高压保证监测器可以长期稳定运行。基于LabVIEW和ROOT编译了集成的PCI数据获取系统,实时在线显示监测结果。根据电子学信号特点,合理安装监测器高压、气体、电子学,减小测试系统开支。完成安装调试后进行长时间监测,并报告了初步的测试结果。
By monitoring the 5.9 keV X-ray of SSFe radioactive source, we develop a counter to monitor the real-time gas ratio of BESⅢ MUON detector. After several experiments to study the performance of the counter, we confirmed the finite proportional mode of our monitor, and chose the appropriate high voltage to make the monitor operate perrnanentIy and stably. Based on LabVIEW and ROOT, we compile the integrated data acquisition system to display the real time monitor result, According to the signal character, we assemble the high voltage, gas pipe and electronic package board to reduce the cost of system equipments. Finally we report the primary test result after assembly.
