Abstract

In-beam evaluation of a fully-equipped medium-size 30 30 cm2 Resistive Plate WELL (RPWELL) detector is presented. It consists here of a single element gas-Avalanche multiplier with Semitron ESD225 resistive plate, 1 cm2 readout pads and APV25/SRS electronics. Similarly to previous results with small detector prototypes, stable operation at high detection efficiency (> 98%) and low average pad multiplicity (1:2) were recorded with 150 GeV muon and high-rate pion beams, in Ne=(5%CH4), Ar=(5%CH4) and Ar=(7%CO2). This is an important step towards the realization of robust detectors suitable for applications requiring large-Area coverage; among them Digital Hadron Calorimetry.
