Instrumentation and Detectors 2023-07-19 v2

Abstract

We present a new design and assembly procedure of a large-area gas-avalanche Resistive-Plate WELL (RPWELL) detector. A 50×50 cm250\times50 ~\mathrm{cm^2} prototype was tested in 80 GeV/c\mathrm{80 ~GeV/c} muon beam at CERN-SPS, presenting improved performances compared to previous ones: MIP detection efficiency over 96\% with 3\% uniformity across the entire detector area, a charge gain of 7.5×103\mathrm{\approx{7.5 \times 10^3}} with a uniformity of 22\%, and discharge probability below 106\mathrm{10^{-6}} with a few single hotspots attributed to production imperfections. These results pave the way towards further up-scaling detectors of this kind.
