Re-commissioning campaign

This report outlines the re-commissioning campaign for P8 warm magnets and circuits in the LHC injectors, specifically focusing on the magnets located in UJ88, UJ87, RA87, and RH87. Tests were conducted successfully in week 16, covering WIC-Magnets and WIC-PC systems. Key activities included individual powering sequence runs, verification of interference with LHC compensators, and a 24-hour heat run that demonstrated acceptable results. Additional preparations are ongoing for the scheduled short circuit tests in P6, addressing minor issues encountered.

  3. P8 WM Tests • Tests performed on week 16 • WIC-Magnets, WIC-PC (Pierre D.) • Done successfully for all magnets/circuits • PC tests (Hugues) • Powering sequence run for all magnets individually • Interference between LHC compensator (SVC) and TI8 PCs to be verified • Heat run (Pierre T.): • 24 h run for LHC magnets and septa. Result OK (T<50 C) • Current versus OK • Magnet polarity OK

  4. Schedule

  5. P6 Short Circuit Tests • RQ4.L6 and RQ4.R6 (UA63 and UA67) • Preparation work ongoing (EL and CV), to be ready for Tuesday morning (one day delay due to missing loctite on rotative joint on WCC) • Deconsignation and balisage by Gerard • PC preliminary tests at 12.00 on Tuesday • Heat run 14.00-22.00
