Description
During LHC 2010 run, approximately 40 experimental sessions for optics Measurements were carried out. Both local and global corrections were implemented demonstrating the feasibility of achieving 10% peak beta-beating. The long-term optics stability is presented with extrapolations of errors down to beta* of 0.55 m. Operational issues arising during corrections, as the treatment of hysteresis, will also be discussed.
