Experiment activities during ramp-up

Activities agreed with experiments

Step ATLAS CMS LHCb ALICE
4b/12b sub-systems commissioning
>= 7h at 4b step
>= 6.5h at 12b step
  mini-VdM in the 12b fill (~30 minutes), first VELO closing leveling at
1 kHz at 4b step
10 kHz at 12b step
75b 15 points emittance scan pair* 15 points emittance scan pair*
~3h at low-mu (mu = 1)
mu-scan + SMOG2 injection zero-field data taking (>= 5h)
400b   backup for low-mu if 75b fails VELO (full) tomography + SMOG2 injection  

*emittance scan pair to be repeated at first two fills of each intensity step
