Description
In order to meet the requirements of high-rate and high time resolution in future high energy physics experiments, a prototype of gaseous photodetector with RPC structure was developed in this paper. The performance of the detector was simulated in Garfield++, and the single-photoelectron performance in different gases was tested using ultraviolet laser. The detector useed a low resistivity (~ 1.4e10 Ω ∙cm) float glass, so that it has high-rate capability, the laser test results show that in MRPC gas, the single-photoelectron time resolution is best to reach ~20 ps at a gain of ~7e6 Qe. This detector can quantitatively test the single-photoelectron performance of different gases, and will be used to find eco-friendly MRPC gases.
