在LHC的CMS实验中，电阻板室（RPC）被用作枪管和端盖中的专用触发系统。本说明介绍了2011年数据采集期间RPC探测器均匀性和稳定性的结果，以及2012年数据获得的初步结果。探测器的均匀性通过LHC碰撞的专用高压扫描来确保，以确定CMS中安装的每个RPC室的最佳工作电压。重点介绍了高压校准的过程和结果。此外，通过自动考虑CMS洞穴中的温度和大气压力变化，提高了探测器的稳定性。
The Resistive Plate Chambers (RPCs) are employed in the CMS experiment at the LHC as dedicated trigger system both in the barrel and in the endcap. This note presents results of the RPC detector uniformity and stability during the 2011 data taking period, and preliminary results obtained with 2012 data. The detector uniformity has been ensured with a dedicated High Voltage scan with LHC collisions, in order to determine the optimal operating working voltage of each individual RPC chamber installed in CMS. Emphasis is given on the procedures and results of the High Voltage calibration. Moreover, an increased detector stability has been obtained by automatically taking into account temperature and atmospheric pressure variations in the CMS cavern.
