Presentation transcript:

Saturday 10:00: Cryo Pt8 back, starting the pre-cycle. 11:00 LHC ready, but SPS bump kicker problem – switch exchange + reconditioning. 15:00 Injecting ! LBDS arming issues (self trigger). Checked by experts but not understood. We manage to carry on. 16:00 Pt8 compensator off. 17:00 We decide to carry on as repair lengthy (2 ½ hours) and we can live without. 18:00 POPS off. 19:30 Filling again. Problem with losses at injection. B1 dumped with 144b. 9/14/2019 LHC 8:30 meeting

Saturday 20:30 BA2 & BA5 flooded – SPS off. 22:00 S81 and S78 switched off – water alarms in Pt8, later also in Pt2 and 1.8. 02:00 Inspections show that there is no water in the LHC buildings. 9/14/2019 LHC 8:30 meeting
