Thursday Physics fill 1250 (with 13b) dumped at 10.30 BLM crate exchange IR7 (10.30 to 17.00) Exchange of crate, check of fibre connections, check of dump request lines, check connections to BIS, etc CMS and ATLAS access in the shadow Beam again from 17.00 Quick attempt to clean up multi-bunch injection Beam 2 is OK Beam 1 losses .. Need to sort this out tomorrow Physics fill with 25b Try hybrid filling scheme B2 4 4 1 4 4 4 4 B1 4 4 1 4 12*1 Beams dumped just before 08.00 (single BLM in 5) 2/22/2019 LHC status

Giulia on shift We are filled !!! 25 on 25 ! We used the Multi_25b_16_16_16_hyb scheme. The following buckets are filled: B1: 1 1001 2001 3001 4001 5001 6001 7001 8001 8941 9941 10941 11941 12941 13941 14941 15941 17851 18851 19851 20851 21851 22851 23851 24851 B2: 1 1001 2001 3001 4001 5001 6001 7001 8501 8911 9911 10911 11911 12911 13911 14911 15911 17851 18851 19851 20851 21851 22851 23851 24851

Thursday Filling 25b Very good for TI8/B2 – in 4b groups. Close to BLM limits for TI2/B1 – even with single bunches. And it worked !!! 2/22/2019 LHC status

Thursday Ramp, squeeze, collide OK 1.2 MJ Peak L seen just after colliding ~2.8E30 cm-2s-1 In STABLE BEAMS peak L ~2.6E30 cm-2s-1 TOTEM RPs at 30/25 sigma (H/V) 1.2 MJ 2/22/2019 LHC status

Friday Morning Afternoon and weekend Multibunch injection studies (Beam 1) Afternoon and weekend Physics with 25 on 25 2/22/2019 LHC status

Interventions needed Magnetic probes in the machine for the studies related to the hump - access would be required in point 5 (GA, LW) 2 hours in the shadow 2/22/2019 LHC status
