| Abstract | In this MD we have driven all collimators from relaxed settings, used routinely during the 2011 operation, to tight settings (primary collimator at 4 nominal sigma) during the ramp and squeezed to beta* = 1.0 m. The tertiary collimators (TCTs) in IR1 and IR5 were then aligned both with noncolliding and colliding beams. After the alignment, loss maps were performed in order to qualify the cleaning for physics operation. |
