Beam Transfer to LHC with the Low Gamma-transition SPS Optics

A new optics was introduced in the SPS for improv- ing beam stability at high intensity. For transferring the beam to the LHC, the extraction bumps, extraction kick- ers and transfer lines needed to be adapted to the new op- tics. In particular, the transfer lines were re-matched and re-commissioned...

Sumario:A new optics was introduced in the SPS for improv- ing beam stability at high intensity. For transferring the beam to the LHC, the extraction bumps, extraction kick- ers and transfer lines needed to be adapted to the new op- tics. In particular, the transfer lines were re-matched and re-commissioned with the new optics. The first operational results are discussed for the SPS extraction, the transfer lines and the LHC injection. A detailed comparison is pre- sented between the old and the new optics of the trajecto- ries, dispersion, losses and other performance aspects.
