/ Bencivenni, G (Frascati) ; De Oliveira, R (CERN) ; Felici, G (Frascati) ; Gatta, M (Frascati) ; Giovannetti, M (Frascati ; INFN, Rome2) ; Morello, G (Frascati) ; Poli Lener, M (Frascati)
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.

The micro-RWELL detector for the LHCb Muon system phase-2 upgrade
/ Bencivenni, Giovanni (CERN) ; De Oliveira, Rui (CERN) ; Felici, Giulietto (Frascati) ; Gatta, Maurizio (Frascati) ; Giovannetti, Matteo (Frascati ; Rome U., Tor Vergata) ; Morello, Gianfranco (Frascati) ; Poli Lener, M (Frascati)
The micro-RWELL is a single amplification stage resistive Micro-Pattern Gaseous Detector, realized with a copper-clad polyimide foil patterned with a micro-well matrix and coupled with the readout PCB through a DLC resistive film ($10\div100$ MOhm/$\square$).
The detector is proposed for several applications in HEP that require fast and efficient triggering in harsh environment (LHCb muon-upgrade), low mass fine tracking (FCC-ee, CepC) or high granularity imaging for hadron calorimeter applications (Muon collider).
For the phase-2 upgrade of the LHCb experiment, proposed for 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. [...]

The micro-Resistive WELL detector for the phase-2 upgrade of the LHCb muon detector
/ Morello, G (Frascati) ; Bencivenni, G (Frascati) ; De Oliveira, R (CERN) ; Felici, G (Frascati) ; Gatta, M (Frascati) ; Poli Lener, M (Frascati) ; Ochi, A (Kobe U.)
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/cm$^2$). [...]

The R&D; on the micro-Resistive-WELL ($\mu$-RWELL) detector technology aims in developing a new scalable, compact, spark-protected, single amplification stage Micro-Pattern Gas Detectors (MPGD) for large area HEP applications as tracking and calorimeter device as well as for industrial and medical applications as X-ray and neutron imaging gas pixel detector. The novel micro- structure, exploiting several solutions and improvements achieved in the last years for MPGDs, in particular for GEMs and Micromegas, is an extremely simple detector allowing an easy engineering with consequent technological transfer toward the photolithography industry.
