北京谱仪桶部簇射计数器的改进升级
Upgrade on the Barrel Shower Counter at BES
【摘要】 描述了北京谱仪桶部簇射计数器(BanelShowerCounter)的改进升级工作,改进后的桶部簇射计数器在能量分辨和位置分辨方面有了明显的提高,经对Bhabha事例进行离线刻度后,能量分辨好于21%,z向位置分辨小于3cm.
【Abstract】 An upgrade has been Performed on the barrel shower counter at Beijingspectrometer to improve the Performance of this detector. For Bhabha events, theenergy resolution is better than 21% (E in GeV) and the spatial resolution alongz axis is smaller than 3cm.
