4. Weekly Lab Status for Magnets Sector Summary • LCLS II – SPQA104 shipped to Jefferson Lab. Repair of LCLS-II magnet SPQA105 completed, preparations for cryogenic tests, good progress on the second top head fabrication for Stand 3 • LARP - Vacuum epoxy impregnation of the first 4.2-m, production length coil, QXFA101 is complete. Completed load testing of the new LARP Top Plate assembly, started mechanical and electrical integration for testing of the LARP 2-m long magnet MQXFS1c • Last week the MQXFA1 (1st 4-m long) conductor and coils readiness review was completed. • AS – Preparation for the first coil epoxy impregnation for the Muon g-2 EDWA magnet (spare) is in progress. • Mu2e – Making steady progress on the TS coil module test facility. Completed cryo piping connections, insulation, and electrical instrumentation of Transport Solenoid prototype on dished head #A, for installation into cryostat next week. The SC lab measured the critical current (Ic) of two cable samples for DS solenoid as part of the QA program. • PIPII – Medium Energy Beam Transport (MEBT) triplets received from India (BARC), assembled on the stands, one triplet is ready for magnetic measurements • G-2 – Inflector parts are prepared for winding, tooling is finalized, the delivery of the NbTi shield material from Japan to Fermilab is being discussed. • 15T dipole R&D – Conceptual design studies of 15-16 T dipoles continue – first results on stress management in cos-theta coils were presented at the US Magnet Development Program (MDP)-FCC-EuroCirCol video meeting. Layer 3 winding completed in the first coil • Infrastructure – removing old Tevatron equipment, feeder cables for TeVtest stand power system were disconnected Weekly Lab Status for Magnets Sector
