Resistive Micro-Pattern Gaseous Detector (MPGD) technologies, such as Micro-Mesh Gaseous Structure (Micromegas), Micro Resistive WELL (uRWELL), and Resistive Plate WELL (RPWELL), are single-stage amplification detectors where signals are induced on the readout electrode through a resistive material. While these technologies have been extensively studied for various applications, their performance has not been systematically compared under similar controlled conditions using an identical readout scheme. In this study, we present the first comparative results on the characterization of Micromegas, uRWELL, and RPWELL detectors.



The characterization is conducted using a laboratory cosmic test bench and the SPS NA H4 beam facility, employing a common setup with VMM3a/SRS readout . Key performance parameters evaluated include:

• detection efficiency


• charge and time response


• pad multiplicity


• gain uniformity


• electrical stability


• rate capability

Additionally, the characterization is performed considering the potential application of Resistive MPGDs in Digital Hadron Calorimetry (DHCAL).

Our findings facilitate informed choices for their application in various experimental scenarios, including DHCAL.
