  1. LHC StatusTueMorning24-July Bernhard Holzer, Mike Lamont LHC 8:30 meeting

  2. MonMorning • 10:10h beam dump ... after a nice long run • Access for ATLAS • Vacuum point 2 (switch back two pumps) • ... & CMS

  3. Mo Morning /Late 11:15h Firebrigadeacces for a fire alarm in point 2 (UW25) -> electrical problem at a water cooling pump -> exchange 12:00h all other access finished ... LHCb ? 18:40h restart 20:20h injection probe beam 20:40h injection for physics ... “Steering problem in Transferlinefor B1H IQC latched on TL oscillation. The oscillation at the beginning of TL seems to be too big, two BPMs are out of threshold for 5 bunches (out of 6).”

  4. MonLate emittances: B1H = 1.66 B1V = 1.57 B2H = 1.40 B2V = 1.16 21:30h ramp, squeeze , adjust, no problems ;-) LHC 8:30 meeting

  5. MonNight • baby sitting • (in a double sense)

  6. Plan: • internal (!)bsbs meeting (beam stability brain storming) • check carefully the Q / Q’ during adjust / squeeze • check separation & x-angles in all IPs • LHCb polarity flip • push single bunch intensity • ?? in one go ??
