Environmental dependence of the performance of resistive plate chambers

Abstract

This paper reports on the performance of Resistive Plate Chambers (RPCs) as function of the gas flow rate through the chambers and of environmental conditions, such as atmospheric pressure, ambient temperature and air humidity. The chambers are read out by pads with an area of 1×1 cm 2 and 1-bit resolution per pad (binary readout). The performance measures include the noise rate as well as the detection efficiency and pad multiplicity for cosmic rays. The measurements extended over a period of almost one year and are sensitive to possible long-term aging effects.

Density muon radiography of La Soufrière of Guadeloupe volcano: comparison with geological, electrical resistivity and gravity data

“…Based on our experience, we expect that other types of detectors like resistive plate chambers would be difficult to control given temperature and humidity variations between night and day (e.g. Ahn et al 2000; Zhang et al 2010). The removal of any background noise is an issue of a great importance when performing absolute density radiography as in this study.…”

Experimental tests of particle flow calorimetry

“…Due to the higher elevation of the CERN site, the RPCs showed a higher gain at CERN than at Fermilab (see also (Bilki et al, 2010) for details on the environmental dependence of the RPC response). To obtain a similar performance, the default high voltage was decreased from 6.3 to 6.1 kV (CALICE, 2012a).…”

Response of the DHCAL to Hadrons and Positrons

“…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].…”
