Abstract

In this article, we report the simulated response of timing RPCs of different gas gaps. A 3D Montecarlo code was developed and integrated with Garfield++ to simulate the avalanche processes with space charge effects which allow actual charge and timing spectrums. The results of this study are presented with examples of timing RPCs of gas gaps 0.02 cm and 0.03 cm.
