Abstract

A challenging goal of 20 ps for the total time resolution of the Multi-gap Resistive Plate Chambers (MRPCs) system has been recently addressed by high energy physics experiments. In order to meet this requirement, one should have a deeper understanding of the detector physics and the factors that contribute to the intrinsic time resolution of the MRPC, which are studied in this paper. The sources of the timing uncertainties, their influences and the relationship with the detector geometry are analyzed. A comparison between the time resolutions obtained using two different simulation algorithms is presented. The obtained results are useful for the design of the timing MRPCs with an improved performance, and meanwhile offer guidance for the R&D activities in the field.
