Abstract

Losses at SPS flat bottom with the LHC proton beams had been studied since the earliest days the LHC beams became available in the SPS. Some of the loss mechanisms involved could be identified and over the years of operation with the nominal 25 ns LHC beam, the losses could be gradually reduced. Nevertheless, in machine studies with high intensity 25 ns LHC beams it is still observed that the transmission degrades with intensity. As summarised in this paper, a series of studies have been performed in 2016 with the aim of further  characterising the loss mechanisms and eventually finding mitigation measures in view of the LHC injector upgrade project (LIU).
