Summary of Injection pre-cleaning tests performed on October 27, 2010

During the LHC filling, in order to reduce the particle losses coming from the un-bunched circulating beam, pre-cleaning of the injection slot has been tried. The cleaning of the injection slot, using 3 s pulse starting from the first bunch of the next batch injection, was performed before the inje...

description During the LHC filling, in order to reduce the particle losses coming from the un-bunched circulating beam, pre-cleaning of the injection slot has been tried. The cleaning of the injection slot, using 3 s pulse starting from the first bunch of the next batch injection, was performed before the injection of the requested batches. The cleaning was then moved to the next injection slot, just prior to the on-going injection request. The results were extremely encouraging, showing much less particle losses when both the cleaning of the injection slot and the abort gap are active and preventing diffusion of uncaptured beam into the injection slot.
