Production of thin-gap Resistive Plate Chambers for the Phase-2 Upgrade of the ATLAS muon spectrometer — Nayana Bangaru, •Francesco Fallavollita, Oliver Kortner, Hubert Kroha, Giorgia Proto, Daniel Soyk, Timur Turkovic, and Elena Voevodina — Max Planck Institut für Physik - Werner Heisenberg Institute, München, Germany
The present ATLAS RPC system will undergo a major upgrade for the HL-LHC program, consisting in three additional full coverage layers of new generation thin-gap RPC trigger chambers, to be installed in the inner barrel region of the Atlas Muon Spectrometer. The Max Planck Institute for Physics (MPI) has established RPC production procedures compliant with industrial requirements and is in the process of certifying several companies for the future RPC series production for the ATLAS upgrade for HL-LHC and beyond. In order to certify the new manufacturers, several 40 × 50 cm2 small-size detector prototypes have been built by them. Their performance have been studied in laboratory tests and at CERN Gamma Irradiation Facility (GIF++). Several full-scale prototypes are currently under construction and qualification at the external manufacturers and at MPI. The prototypes will undergo long-term irradiation for half a year in the CERN GIF++ facility in order to qualify the components and production procedures with respect to longevity. The core of the project is presented, together with a description about the technology transfer, the RPC prototype production and certification at the selected companies, as well as their performance and stability measurements at CERN GIF++ facility.
