  1. Last night • 12:00 TDI Xray finished • 13:00 TED check finished • 14:00 Beam Loop closed • 14:30 Not possible to perform the injection beam interlock test for MKI • SPS Beam LOOP open due to Vacuum intervention. • 14:30 Continue LBDS tests in the LHC ring • 18:30 Access Vacuum gauge problem on MKI8 finished. • 19:00 Vacuum interlock tests finished. • 19:17 Ramp squeeze and collision all circuits without problems. • 20:00 Switch ON Exp’s compensator RBWMDV.L2 faulty • 22:30 Collimators through the ramp and squeeze • While loading injection settings, sector 81 did not load as one circuit timed out:RCBV13.L1B1 • RF cavity ACSMOduleM1B2 tripped. According to cryo it was a small quench

  2. Last night • High-Beta squeeze still some problem when loading the function. • Totem settings ok for the nominal injection.

  3. Open issues • SPS Vacuum leak in Ba1 • Vacuum level 1E-5 Bar • RCBXH1.L1 • ramp rate changed to 4.5 > 3.5 A/sec • Acceleration 0.25 > 0,2 A/sec^2 • RQTD/F circuits unable to load ramp/squeeze function • RQF/RQD require higher commissioning current for high beta (50 A) LSA table updated • Now at from 6400 >> 6450 A • Exp’s compensator RBWMDV.L2 faulty • 2 final tests for LBDS & Kicker to be operational

  4. Lbds test •  12:00 Synchronisationof injection and AGK tests (EC, WB)-          • 13:00 Injection BETS checks and Soft Start limits tests (MB, WB)
