Beam collimation and control in the LHC high energy injectors

The design and construction of new injectors will allow to boost the luminosity of the LHC. Two consecutive machines capable to inject into the LHC ring at 1 TeV are being considered. Based only on the expected performance of the injectors, the beam loss handling in these high intensity machines will be a challenge and the introduction of collimation systems seems necessary. The need to reduce the beam losses and allow an efficient collimation system has to be implemented from the beginning of the design. The energy ramping in stages requires different approaches for removing the proton halo. Some studies are still necessary to define the hardware. The study performed in this paper as well as the conclusions will only slightly differ when applied to another scenario.
