The small-diameter Drift Tube (sMDT) Chambers for ATLAS at High-Luminosity LHC and for Future Colliders — Davide Cieri, Gregor Eberwein, Oliver Kortner, Hubert Kroha, Patrick Rieck, Marian Rendel, and •Elena Voevodina — Max-Planck-Institut für Physik, München, Deutschland

The small-diameter Drift Tube (sMDT) detector technology with 15 mm tube diameter has proven to be an excellent candidate for precision muon tracking detectors in experiments at future hadron colliders like HL-LHC and FCC-hh where unprecedentedly high background rate capabilities are required. The upgrades of the inner barrel layer of the ATLAS Muon Spectrometer in the LS2 (2019-2021) and LS3 (2026-2028) shutdowns of the LHC machine use combinations of the sMDT detectors and RPC trigger chambers. We present the test results of the performance of the sMDT chambers under construction for the operation at HL-LHC and the measurements of the behavior of the detectors and their new readout electronics under very high background irradiation rates like at FCC-hh performed at the CERN Gamma Irradiation Facility (GIF++).
