IT-4661/EP/ATLAS - Supply of Regulated Extra-low, Low and High Voltage Power Supplies for the Phase 2 ATLAS Muon Spectrometer

This Technical Specification concerns the supply and maintenance of regulated Extra-low (ELV)1, Low (LV)2 and High (HV)3 Voltage DC Power Supplies of the ATLAS Muon Spectrometer, necessary to power its detectors and front-end/read-out electronics. These power supplies will be installed during the LHC Long Shutdown 3 (2026 – 2028) and beyond (up to 2030). The contracts will be awarded in three separate lots:  Lot 1 – Monitored Drift Tubes (MDT) and Small Monitored Drift Tubes (sMDT) ELV, LV and HV power supplies, and Small Thin Gap Chambers (sTGC) HV power supplies;  Lot 2 – Thin Gap Chambers (TGC) ELV, LV and HV power supplies;  Lot 3 – Legacy Resistive Plate Counters (RPC) and Barrel Inner (BI) RPC ELV, LV and HV power supplies.
