comments:
-
Systematic B1 issues: blow-up on 1st two bunches of every 2nd 36b train.
-
Later the 12 non-colliding bunches went unstable; chroma +15 finally stabilized B1.
-
Number of bunches in beam 1 445 vs beam 2 447
-
fake jumps in the lumi of ATLAS (not physical, not observed o BRAN)
-
beta* levelling got interrupted for half an hour as the server got stalled when moving from 30cm to 27 cm beta*
