“…Compared to other technologies explored under similar conditions, the performance of the 10×10 cm 2 RPWELL detector reported in this work, with respect to detection efficiency and pad multiplicity, is better than that of 1×1 m 2 RPCs [41,42] and 30×30 cm 2 GEM detectors [43] and similar to that of 1×1 m 2 MICROMEGAS [44,45].…”

We present the results of the first in-beam studies of a medium size (10×10 cm 2 ) Resistive-Plate WELL (RPWELL):a single-sided THGEM coupled to a pad anode through a resistive layer of high bulk resistivity (∼10 9 Ωcm). The 6.2 mm thick (excluding readout electronics) single-stage detector was studied with 150 GeV muons and pions. Signals were recorded from 1×1 cm 2 square copper pads with APV25-SRS readout electronics. The single-element detector was operated in Ne/(5%CH 4 )at a gas gain of a few times 10 4 , reaching 99% detection efficiency at average pad multiplicity of ∼1.2. Operation at particle fluxes up to ∼10 4 Hz/cm 2 resulted in ∼23% gain drop leading to ∼5% efficiency loss. The striking feature was the discharge-free operation, also in intense pion beams. These results pave the way towards robust, efficient large-scale detectors for applications requiring economic solutions at moderate spatial and energy resolutions.

“…Compared to other detector technologies explored under similar conditions, e.g. for the DHCAL, the performance of the 10×10 cm 2 RPWELL detector, with respect to detection efficiency and pad multiplicity, is superior to that of 1×1 m 2 RPCs [17,19] and 30×30 cm 2 GEM detectors [20]; it is similar to that of 1×1 m 2 MICROMEGAS [21,22]. The efficiency dependence on the incoming particle flux is similar to that of multi-gap RPCs based on semi-conductive glass [23].…”

A thin single-element THGEM-based, Resistive-Plate WELL (RPWELL) detector was operated with 150 GeV/c muon and pion beams in Ne/(5%CH 4 ), Ar/(5%CH 4 ) and Ar/(7%CO 2 ); signals were recorded with 1 cm 2 square pads and SRS/APV25 electronics. Detection efficiency values greater than 98% were reached in all the gas mixtures, at average pad multiplicity of 1.2. The use of the 10 9 Ωcm resistive plate resulted in a completely discharge-free operation also in intense pion beams. The efficiency remained essentially constant at 98-99% up to fluxes of ∼10 4 Hz/cm 2 , dropping by a few % when approaching 10 5 Hz/cm 2 . These results pave the way towards cost-effective, robust, efficient, large-scale detectors for a variety of applications in future particle, astro-particle and applied fields. A potential target application is digital hadron calorimetry.

“…Detection elements based on the MICRO MEsh GAseous Structure (MICROMEGAS), tested with muons at 1 m 2 units, displayed superior properties (with a thickness of ∼ 3.1 mm, excluding the MICRO-ROC electronics [15]): 97% efficiency with a 1.1 average multiplicity [16]. Detector prototype using 30 × 30 cm 2 double Gas Electron Multipliers (double-GEMs) of 5 mm thickness excluding the KPiX readout electronics [17], yielded a multiplicity of 1.3 at 95% efficiency with muons [18].…”

Beam studies of novel THGEM-based potential sampling elements for Digital Hadron Calorimetry

Beam studies of thin single-and double-stage THGEM-based detectors are presented. Several 10 × 10 cm 2 configurations with a total thickness of 5-6 mm (excluding readout electronics), with 1 × 1 cm 2 pads inductively coupled through a resistive layer to APV-SRS readout electronics, were investigated with muons and pions. Detection efficiencies in the 98% range were recorded with an average pad-multiplicity of ∼ 1.1. The resistive anode resulted in efficient discharge damping, with few-volt potential drops; discharge probabilities were ∼ 10 −7 for muons and 10 −6 for pions in the double-stage configuration, at rates of a few kHz cm 2 . These results, together with the robustness of THGEM electrodes against spark damage and their suitability for economic production over large areas, make THGEM-based detectors highly competitive compared to the other technologies considered for the SiD-DHCAL.
