A high rate and precise timing photo-RPC with low-resistivity float glass

The electrode's resistivity is crucial for resistive gaseous detectors' rate capability. We developed a precise timing gaseous photodetector with a glass RPC structure (photo-RPC). The detector's rate capability and timing performance were measured with different resistive float glass. The results show that compared to the photo-RPC with a high-resistivity electrode, the detector with very low-resistivity (1.5 × 10 9 Ω·cm) glass shows greatly improved rate capability, while the time resolution and gain remains unchanged.
