1. Monday 12.7 03:00 Stable beams 9_6_6_6 13:40 Access.
09:40 back to ADJUST to switch on damper and switch off octupoles.
10:20 back to STABLE BEAMS.
11:57 beam dumped by LHC VELO when switching back to ADJUST mode after ADJUST handshake. VELO was not fully out.
End of a very good fill, luminosities still at 7E29. No problem with damper in stable beams.
13:40 Access.
S12 QPS fixed.
FMCM threshold increase on RMSD.B1(2). Up by a factor ~ 4 at injection. Rough test with beam is OK (vertical shift of 3 mm on BTV in front of TDE). To be repeated with a complete OFF to the PC (injection).
RF access in P4.
8:30 meeting

2. Tune spectra damper On-Off
8:30 meeting

3. Monday 12.7 10:00-17:00 SPS multi-bunch cycle
Continued setting up of the cycle with 4 injections. Emittances below nominal.
Adjusted extraction kicker delays to extract ALL 4 bunches.
Extraction to upstream TEDs for both B1 and B2.
Extraction to TI2 downstream ok.
Everything looking ok – next step is injection into the LHC.
15:00 LHCb with - polarity
17:00 TDI P2 problem
Does not reach requested setting. Mechanical problem to be fixed today.
TDI in position with help of the piquet.
17:30 Injection
Large orbit perturbation from LHCb polarity inversion – large local kick at MCBX.1R8.
8:30 meeting

4. Monday 12.7 19:30: Filling 12_8_8_8 9E10/bunch 20:00: Ramp
20:45: Flat top
Incorporated RT trims from orbit into settings/functions. Worked partly only – anything changed in the past 2 weeks???
When the OFB was switched off, the settings of the RT suddenly jumped to NaN for all vertical orbit correctors (????????), horizontal plane OK.
Switching ON/OFF OFB seemed to indicate that it was still working…
21:20 Squeeze
Beam lost due to vertical orbit change: the OFB did not act in vertical.
Beam dumped by losses in IR7 (84 s RS on MQWA).
23:00 Setup
MKI problem IR8 – faulty after pressure rise.
00:30 Injection
8:30 meeting

5. Tuesday 13.7 02:00: Again some issue get the OFB ON 02:30: Ramp
04:00: Squeeze
OFB off by itself while squeezing. Orbit change moderate and beam survived. Manual correction at 7 m, then OFB on again.
05:20 Stable beams fill 1224
L  1.4E30 cm-2s-1.
Some beam loss after ATLAS lumi scan.
Strong losses correlated with lines at in Q spectrum.
8:30 meeting

6. Fill 1224
8:30 meeting

7. Tune spectrum lines…
8:30 meeting

8. Tuesday 13.7 Keep this fill for some time, try again damper.
Multi-bunch injection studies later today.
Fill overnight.
Check OFB issues during the day (start with offline checks).
8:30 meeting
