Optics commissioning for the first p-Pb run in the LHC

The first physics production with asymmetric p-Pb collisions in 2013 required a complex machine commissioning to be done in a very short time after the Christmas technical stop. A substantial part of this was the commissioning of the newly created squeeze process to $\beta$*= 0:8m at IP2, as well as IP1 and IP5, and $\beta$*= 2.0 m in IP8, the lowest value ever provided at LHCb. It was necessary to make all tests off-momentum in both positive and negative directions to prepare for both p-Pb and Pb-p configurations. Using protons in both rings, the commissioning was carried out successfully in three days.
