羊八井中RPC探测器的性能测试

Performance of RPCs operated at the Yangbajing Laboratory

    摘要
  • 摘要: 中意合作组在羊八井ARGO实验中采用大型RPC阵列探测广延大气簇射事例(AS);报告了在羊八井高海拔条件下,RPC的工作性能、探测器系统工作参数,其中包括探测效率随高压变化、读出条多重数和时间分辨率等,并研究加入SF6气体与改变系统阈值这2种新方法消除系统噪声和压低二次流光放电,实验研究取得良好结果,满足ARGO实验所需的探测器性能要求,为后续的ARGO实验打下了关键性基础.

     

    Abstract: The ARGO-YBJ experiment will be installed at YangBajing Cosmic Ray Laboratory (Tibet,(4?300?m) a.s.l).A small test of has been operated at Yangbajing in order to study the RPC performance and detector parameters in these high altitude conditions.By adding SF6 component into the gas mixture to limit the streamer development together with changing the threshold of the signal-receiving system,the detector noise effect is effectively eliminated,thus achieving lower strip multiplicity and lower working parameters under the same working high voltage.Results concerning efficiency,time resolution and strip multiplicity are reported.
