Experimental and Numerical Studies of the Efficiency of Gaseous Detectors

We have estimated the gain and efficiency of resistive plate chambers experimentally, as well as numerically. The experimental setup has a stack of three plastic scintillators and a detector. We have calculated threefold and 4-fold efficiency of RPC with respect to plastic scintillators by designing a FPGA-based DAQ (Hu in Nucl Instr Methods Phys Res A, 2011). Garfield++ has been used in various possible modes to numerically simulate the detector response of RPCs. The results have been compared and attempts have been made to interpret their nature.
