Abstract

We present a comparative study of three resistive Micro-Pattern Gaseous Detector (MPGD) technologies - Micromegas, RPWELL, and μRWELL\mu\mathrm{-RWELL} - with VMM3a based readout, using relativistic muons and pions. The Micromegas and the RPWELL were operated in Ar/CO2/iC4H10\mathrm{Ar/CO_2/iC_4H_{10}} gas mixture, while the μRWELL\mu\mathrm{-RWELL} in Ar/CO2/CF4\mathrm{Ar/CO_2/CF_4} (greenhouse gas containing mixture). All detectors operated stably exceeding 96% efficiency. The usage of continuous readout enabled studies of detector electrical instabilities in- and off-beam at near breakdown voltages. Each technology has different advantages making it more suitable for various experimental conditions.
