In this work we present a novel idea for compact spark-protected single amplification stage Micro-Pattern Gas Detector (MPGD). The detector stage, realized with structure very similar to GEM foil, is embedded through resistive layer in the readout board. A cathode electrode, defining gas conversion/drift gap, completes mechanics. new structure, that call micro-Resistive WELL (μ-RWELL), has some characteristics common previous MPGDs, such as C.A.T. and WELL, developed more than ten years ago....
Abstract The forthcoming High-Energy Physics (HEP) experiments necessitate particle detection technologies that are efficient, scalable, and compatible with industrial production. μ-RWELL, a single-stage resistive MPGD based on sequential build-up technology, meets these demands.
