Advances on micro-RWELL gaseous detector

Abstract

The R&D on the micro-Resistive-WELL (µ-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 microstructure, 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. Large area detectors (up 1×2 m 2 ) can be realized splicing µ-RWELL_PCB tiles of smaller size (about 0.5×1 m 2 -typical PCB industrial size). The detector, composed by few basic elements such as the readout-PCB embedded with the amplification stage (through the resistive layer) and the cathode defining the gas drift-conversion gap has been largely characterized on test bench with X-ray and with beam test.

Dual-Readout Calorimetry for Future Experiments Probing Fundamental Physics

“…The preshower is used to identify and measure electromagnetic showers that originate in the material of the solenoid before reaching the calorimeter. The preshower is constituted of a large array of a novel type of micro-pattern gas detectors, the µ-RWELL [33,34]. The preshower provides a spatial resolution for charged particles of about 60-70 µm.…”

Detector geometry management system designed for Super Tau Charm Facility offline software

“…For example, the VTD has two very different design options (see figure 2). In the 𝜇RWell [10] design (figure 2a), 3 layers of 100 μm-thick 𝜇RWell foil acting as an electron multiplier and charge collector constitute the main components of the detector. In the Inner Silicon Detector (ISD) design (figure 2b), silicon pixel detectors or silicon strip detectors serve as the critical components.…”
