ARGO-YBJ实验已经收集了近两年的数据。为了连续监测电阻板室探测器的性能,并研究每日温度对探测器性能的影响,在雅高-北京实验室的地毯式探测器阵列附近安装了一台宇宙射线μ子望远镜。在实际工作电压为7.2kV时,温度对RPC时间分辨率的影响约为0.04ns/μ C,对粒子探测效率的影响约为0.03%/μ C。根据这些数字,我们得出结论,环境效应不会影响实质上的ARGO-YBJ探测器的角分辨率。
The ARGO-YBJ experiment has been taking data for nearly 2 years. In order to monitor continuously the performance of the Resistive Plate Chamber detectors and to study the daily temperature effects on the detector performance, a cosmic ray muon telescope was setup near the carpet detector array in the ARGO-YBJ laboratory. Based on the measurements performed using this telescope, it is found that, at the actual operating voltage of 7.2kV, the temperature effect on the RPC time resolution is about 0.04ns/∘C and on the particle detection efficiency is about 0.03%/∘C. Based on these figures we conclude that the environmental effects do not affect substantially the angular resolution of the ARGO-YBJ detector.
