【摘要】 Resistive Plate Chamber (RPC) modules will be used as one part of the cosmic muon veto system in the Daya Bay reactor neutrino experiment.A total of 189 RPC modules will cover the three water pools in the experiment.To achieve track reconstruction and high efficiency,each module consists of 4 layers,each of which contains two sizes of bare chambers.The placement of bare chambers is reversed in different layers to reduce the overlapping dead areas.The module efficiency and patch efficiency were studied both in simulation and test of the data analysis.143 modules have been constructed and tested.The preliminary study shows that the module and patch 3 out of 4 layers efficiency reaches about 98%.更多还原
