Computation of 3D electrostatic weighting field in Resistive Plate Chambers

Three-dimensional electrostatic weighting field configuration in a typical Resistive Plate Chamber (RPC) has been studied with the neBEM solver which evaluates accurate potential and field distributions in a given chamber following Boundary Element Method (BEM). The variation in three-dimensional weighting field of the RPC has been studied in detail with the change in design parameters like dimension, material, location of several components. The advantage of using the numerical solver neBEM in comparison to analytical solutions and other numerical approaches has been discussed in connection to the evaluation of weighting field.
