Comparative study of resistive MPGD technologies

Abstract Resistive Micro-Pattern Gaseous Detectors (MPGDs) are emerging as promising candidates for high-energy physics applications due to their low material budget, simplified operational schemes, and inherent protection for readout electronics. This work presents a comparative study of three resistive MPGD technologies: Micromegas (MM), micro Resistive WELL ( μ -RWELL), and Resistive Plate WELL (RPWELL). The detectors were tested with muon and pion beams at the CERN SPS facility. Detection efficiency, cluster size, and rate dependency were characterized, revealing distinct performance features for each technology. The MM detector exhibited high efficiency (98%) across all drift fields, while μ -RWELL reached an 84% efficiency plateau due to a large dead area. RPWELL reached a 96% efficiency plateau with a small dead area and showed efficiency loss at high gain.
