“…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.

“…The fits represent the data well and for the longitudinally contained pions -that have no hits in the last two layers-a stochastic term of approximately 55 % and a constant term of 7.5 % is achieved. The measurements are within 1-2 % of predictions [4] based on the simulation of the large-size DHCAL prototype using the vertical slice test (VST) results [4][5][6][7][8].…”

We have constructed a prototype Digital Hadron Calorimeter (DHCAL) using Resistive Plate Chambers (RPCs) as the active elements. The RPCs are read out digitally (1-bit) by 1 x 1 cm 2 pads. The DHCAL consists of 38 alternating layers of steel and RPCs followed by a 14 layer tail catcher (TCMT), also read out using RPCs. With each layer consisting of 9,216 channels, the entire detector contains 350,208 (DHCAL) + 129,024 (TMCT) = 479,232 readout channels (world record in calorimetry). Each active layer contains three 32 x 96 cm 2 RPCs. In this paper we report on results from a first look at the DHCAL data to assess the calorimetric properties of the DHCAL. We present preliminary results from the analysis of both positron and pion events of momenta between 2 and 60 GeV/c. These results are considered to be a first validation of the viability of the DHCAL concept.
