  1. Thursday 10th January 9:30 Network routers restart, all went fine, but only just. 12:00 All power converters from the arcs on at standby 12:00 ELQA test finished Still some selected accesses 17:40 Cryo Maintain OK for all sectors 18:37 Cryo OK complete machine Test of circuits and QPS 22:55 All vacuum valves open 00:48 All HWC tests finished 02:41 BIS loops closed 06:50 RF conditioning M1.B1 finished LHC 8:30 meeting

  2. Network routers restart – IT department • The restart of the routers did affect the LHC • Many cryo valves closed IP8. Stop of compressors just avoided because of the cryo crew was ready to react. • ODH in IP2 (as displayed in CCC) • Linac2 Vistar BCT (trafo) readings • Good that it was a coordinated reboot following yesterday’s request by IT LHC 8:30 meeting

  3. Decided on polarities LHC 8:30 meeting

  4. Outstanding • RF • “Module 1B1 has 2 cavities that need further conditioning overnight. We would make them operational early morning to-morrow.” Finished this morning at 6:50 • RF interlock cav4.B2: piquet called • RF low-level set-up going on right know: 1 hour • Power converters to be changed • 60 A corrector pc RCBV12.L7B2 • 60 A corrector RCBV28.R1B1 • CMS shielding at top of pit? LHC 8:30 meeting

  5. The plan • John’s master plan, as presented yesterday, can be found via “latest news” page. • Today: • RF low-level set-up (1 h) • Change 2 pc (2 h) • Take first beams • Test ramp with dump at flat top • Set-up of squeeze, optics measurements • TDI, BPMS LHC 8:30 meeting
