我们建立了一组氙闪光管-光导纤维装置,作为Mark-J探测装置的计数器监测系统,监测208个光电倍增管的输出,可以随时校正计数器的脉冲输出幅度,并给出计数器系统间的时间关系。由于引入了参考管系统,改善了系统的稳定性,提高了测量精度(±1％),经过长期的运转,证明性能良好,稳定可靠。 We have built a Xenon flash tube - an optical fiber device that acts as a counter monitoring system for the Mark-J detection device and monitors the output of 208 photomultiplier tubes to correct the pulse output amplitude of the counter at any time and gives the time between counter systems relationship. Due to the introduction of the reference tube system, the stability of the system is improved and the measurement accuracy (± 1%) is improved. After long-term operation, it proves that the performance is good and stable.
