The Resistive-Plate WELL with Argon mixtures - a robust gaseous radiation detector

Abstract

A thin single-element THGEM-based, Resistive-Plate WELL (RPWELL) detector was operated with 150 GeV/c muon and pion beams in Ne/(5%CH${}_4$), Ar/(5%CH${}_4$) and Ar/(7%CO${}_2$); signals were recorded with 1 cm${}^2$ square pads and SRS/APV25 electronics. Detection efficiency values greater than 98% were reached in all the gas mixtures, at average pad multiplicity of 1.2. The use of the 10${}^9$Ωcm resistive plate resulted in a completely discharge-free operation also in intense pion beams. The efficiency remained essentially constant at 98-99% up to fluxes of $\sim$10${}^4$Hz/cm${}^2$, dropping by a few % when approaching 10${}^5$ Hz/cm${}^2$. These results pave the way towards cost-effective, robust, efficient, large-scale detectors for a variety of applications in future particle, astro-particle and applied fields. A potential target application is digital hadron calorimetry.
