Production and testing of Resistive Plate Chambers (RPCs) — •Timur Turkovic, Oliver Kortner, Daniel Soyk, and Hubert Kroha — Max Planck Institut für Physik

Resistive plate chambers (RPCs) with electrodes of high-pressure phenolic laminate (HPL) and small gas gap widths down to 1 mm provide a relatively low cost detector for large area tracking in ATLAS, that still grants high rate capability and fast response with an excellent time resolution of better than 500 ps. They can be operated up to γ background count rates of 10 kHz/cm2, which is five times the maximum rate these RPCs will encounter in the innermost layer of the barrel muon spectrometer of the ATLAS detector, where they will be installed in the phase-II upgrade for the HL-LHC operation. Production procedures that were previously developed in the lab have been transferred to several companies of which each produced first test samples. The quality of these samples was tested by measuring the voltage-current curves and the muon detection efficiency with cosmic muons.
