The Induced Charge Signal of Glass RPC Detector

Abstract

The gas detector glass resistivity parallel chamber (GRPC) is proposed to use in the Hadron calorimeter (HCAL), the read-out system is based on the semi-digital system, then the charge information from GRPC is needed. To better understand the charge comes out from GRPC, we started from cosmic ray test to get the charge distribution and then study the induced charge distribution on the collection pad, after successfully compared with the prototype beam test data at CERN (European Council for Nuclear Research), the process was finally implanted into the Geant4 based simulation for future study.
