Studies on Electrical Properties of Resistive Plate Chamber (RPC)

A numerical model based on Finite Element Method (FEM) has been developed to simulate the electrical properties of RPC utilizing the law of current conservation. It has been used to systematically investigate the effect of the electrical as well as the geometrical parameters of the device components on the potential distribution and field configuration which govern the RPC performance. The numerical model has been validated by comparing the dark current and electric field with those produced by another mathematical model based on surface currents. The efficacy of the present model has been demonstrated by comparing its results to the experimental measurements performed with a glass RPC. The measured and estimated values of these observables have been found to be in good agreement.
