Minutes and Summary
Main purpose of the meeting:
Final preparations for media event and experimental requests for ramp-up
1) Introduction (Brian)
slide 3: FASER/SND emulsion exchange : foresee 8 hours instead of 4 hours
Gas injection in SMOG still not in LHCb’s hands, but agreement with vacuum group
to operate on short notice. Will only be hand of LHCb in September.
Q (Widold): will it be ready by VdM scan programme in September.
A (Federico): yes, it’s high priority.
slide 5: beam-beam measurement needs to be scheduled soon, so proponents can plan travel.
slide 6: remaining beam commissioning steps: ~ 5 shifts (daytime).
slide 8: ramping of ALICE magnet: foreseen for end of second fill.
beta* leveling from first fill onwards (evening on July 5th)
slide 9: to be checked if multi bunch indiv injection is set up in injectors
Q (Federico-ALICE): IP2 only offset leveling?
A (Jorg W): yes
2) Round Table
CMS (Gianni)
filling scheme for 900 GeV collisions during the night? A: 4b, 2 colliding.
scrubbing: foreseen to be in 2-3 blocks. To be discussed how to handle it.
ALICE (Federico)
magnet scan test, see slide 3
ATLAS (Jorg)
slide 2: loss maps gave good data. Last one did not take data.
ALTAS plans for intensity ramp up on slide 3.
Q (Jorg S): PU for tomorrow?
A (JW): low 30
Q (Jorg S): AFP insertion today?
A (JW): yes, try it out today.
slide 4: tomorrow: need to bring beam into collision after ADJUST
slide 4: put 2 scrubbing blocks together.
request for horizontal muons no longer needed after this week.
LHCb (Preema)
no change from last week
plan to test VELO safety system end of the week
