Description
Performance of the Gas Gain Monitoring system, installed in 2009 at CMS Experiment, are presented. The GGM is aiming to keep under control the gas quality of the CMS RPC closed loop gas system. To perform this task the GGM is made of single-gap RPCs arranged in a cosmic ray telescope, with charge readout for online monitoring of working point; this provides a fast and accurate determination of any shift of the working point conditions. The GGM is integrated in the main CMS detector control system while the DAQ runs standalone within the standard CMS XDAQ framework. The GGM showed very good sensitivity to gas changes, moreover in the second part of the year we adopted a different algorithm to correct the environmental variables so that performance were enhanced.
