| contents | To meet the need for a high counting rate and high time resolution in future high-energy physics experiments, a prototype of a gas photodetector with an RPC structure was developed. Garfield++ simulated the detector's performance, and the single photoelectron performance of different mixed gases was tested with an ultraviolet laser. The detector uses a low resistivity ($\sim1.4\cdot 10^{10} Ω\cdot cm$) float glass so that its rate capability is significantly higher than that of ordinary float glass($10^{12}\sim10^{14} Ω\cdot cm$), the laser test results show that in MRPC gas($R134a/iC_{4}H_{10}/SF_{6}(85/10/5)$), the single photoelectron time resolution is best to reach 20.3 ps at a gas gain of $7\cdot 10^{6}$. Increasing the proportion of $iC_{4}H_{10}$ can effectively reduce the probability of photon feedback, without changing the time resolution and maximum gain. In addition to being applied to high-precision time measurement scenarios (eg:T0, TOF), the detector can also quantitatively test the single photoelectron performance of different gases and will be used to find eco-friendly MRPC gases. |
