The High-Luminosity LHC (HL-LHC) upgrade represents a challenge for the full chain of its injectors. The aim is to provide beams with a brightness a factor of two higher than the present maximum achieved. The 450 GeV beams injected into the LHC are directly provided by the Super Proton Synchrotron (SPS) via two transfer lines (TL), TI2 and TI8. Such transfer lines are both equipped with a passive protection system to protect the LHC aperture against ultra-fast failures of the extraction and transport systems. In the LHC instead, the injection protection system protects the cold apertures against possible failures of the injection kicker, MKI. Due to the increase of the beam brightness, these passive systems need to be upgraded. In this paper, the foreseen and ongoing modifications of the LHC injection protection system and the TL collimators are presented. Simulations of the protection guaranteed by the new systems in case of failures are described, together with benchmark with measurements for the current systems.

The goal of the HL-LHC is to increase the LHC peak nominal Luminosity by a factor of seven in order to provide more accurate measurements of new particles and enable observation of rare processes that occur below the current sensitivity level. Achieving this target requires to double the beam intensity and reduce the emittance by 40%. All the LHC injectors, from the LINAC to the Super Proton Synchrotron (SPS) including the heavy ion chain, have to be improved to reliably supply such high brightness beams to the HL-LHC. The upgrade campaign will be completed during the Second Long Shutdown (LS2) in 2019-2020. The performance objectives and the status of this challenging program is presented.
