The surface Resistive Plate Counter (sRPC) is a revolutionary RPC based on surface resistive electrodes realized with Diamond-Like-Carbon sputtered on Apical® foil. Exploiting high granularity ...current evacuation schemes developed for resistive MPGD and using electrodes with low surface resistivity (down to ∼100MΩ/□), sRPCs standing particle fluxes up to several hundreds kHz/cm2 should be easily developed. The scalability of the technology allows the construction of detectors for large area applications at future high luminosity colliders.

The micro-RWELL detector (μ-RWELL) is a single amplification stage resistive Micro Pattern Gaseous Detector (MPGD), based on a copper-clad polyimide foil patterned with a micro-well matrix coupled ...with the readout PCB through a DLC resistive film (10÷100MΩ/□). For the phase-2 upgrade of the LHCb experiment, proposed for the LHC Run-5, the excellent performance of the current muon detector will need to be maintained at 40 times the pile-up level experienced during Run-2. Requirements are challenging for the innermost regions of the muon stations: the detectors should exhibit a rate capability up to 1MHz/cm2 and they are supposed to integrate a charge up to ∼1C/cm2. In this framework an intense optimization program of the micro-RWELL technology has been launched in the last year, together with a technology transfer to the industry operating in the PCB field. In order to fulfill the requirements, a new layout of the detector with a very dense current evacuation grid of the DLC has been designed. The detector, co-produced by the CERN-EP-DT-MPT Workshop, lead by one of the authors, and the ELTOS Company, has been characterized in terms of rate capability exploiting a high intensity X-ray Philips 2217/20 gun with a spot size (10÷50mm diameter) larger than the DLC grounding-pitch. A rate capability exceeding 10MHz/cm2 has been achieved, in agreement with previous results obtained with m.i.p. at the Paul Scherrer Institute (PSI) in Villigen (CH). A long term stability test is in progress: a charge of about 5mC/cm2 has been integrated over a period of about 16 days. The test will continue, in harder conditions (larger gain and X-ray flux), with the goal to integrate about 1C/cm2 in one year, while a slice test of the detector is under preparation.

The μ-RWELL is a new generation Micro-Pattern Gaseous Detector, composed of two elements: the cathode and the μ-RWELL_PCB including the amplification stage, realized with a polyimide structure ...micro-patterned with a blind-hole matrix, embedded through a Diamond-Like Carbon (DLC) resistive layer with the readout PCB. Different layouts of the resistive stage have been studied: the simplest one is based on a single DLC layer with edge grounding, suitable for low rate applications (30–40 kHz/cm2). More sophisticated schemes are under study for high-rate purposes (up to 2–3 MHz/cm2) in order to optimize the performance and the constructive process. For the phase-2 upgrade of the LHCb muon detector the experiment is targeting a luminosity of 2×1034 cm−2 s−1, with strong requirements on the robustness and detection efficiency of the muon system. We report on the ongoing R&D, showing also the latest measured performances of the new high-rate versions of the detector.
