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。
Development of counter tube monitor, by monitoring the 55Fe 5.9keV X-ray photoelectric peak, real-time monitoring BES Ⅲ MUON detector gas ratio. After a series of experiments to study the various performance of the counting tube, a clear mode of work for the finite positive model; select the best working pressure to ensure that the monitor can be long-term stable operation. Based on LabVIEW and ROOT compiled integrated PCI data acquisition system, real-time online monitoring results. According to the characteristics of electronic signals, reasonable installation of monitors high pressure, gas, electronics, reducing test system expenses. After completing the installation and commissioning for a long time monitoring, and reported the preliminary test results.
