摘要：The India based Neutrino Observatory (INO) collaboration is planning to build a 50 kton magnetized iron calorimeter (ICAL) detector to study neutrino oscillations and measure their associated parameters. ICAL will use 28,800 glass Resistive Plate Chambers (RPCs) of 2mX2m size, operated in the avalanche mode, as its active detector elements. As a part of detector R & D to develop the RPCs required for this detector, we studied the effect of Sulfur hexaflouride (SF6) on various RPC parameters. In this paper, we present a comparative study of charge development on the RPC pick-up electrodes using simulation and experimental data. The primary interaction parameters of the incident particle in RPC gas volume is calculated using HEED, while the electron transport parameters are computed using MAGBOLTZ. We have used nearly exact Boundary Element Method (neBEM) solver to calculate the weighting field and electric field accurately. Finally, the induced charge is obtained following the Ramo’s theorem.
