EMITTANCE GROWTH IN COAST IN THE SPS

A. Alekou et al.

Abstract


The CERN SPS will be used as a test-bed for the LHC prototype crab-cavities, which will be installed and tested in the SPS in 2018. As the time available for experimental beam dynamics studies with the crab cavities installed in the machine will be limited, a very good preparation is required in advance. One of the main concerns is the induced emittance growth, driven by phase jitter in the crab cavities. In this respect, several machine development (MD) studies were performed during the past years to quantify and characterize the emittance evolution of proton beams in coast in the SPS. In these proceedings, the experimental observations from past years are summarized and the MD studies from 2016 are presented. Finally, a proposal for an experimental program for 2017 is discussed.
