The injector complex of the LHC is undergoing important changes in the light of the LIU project to provide brighter beams to the LHC. For this reason and as part of the High Luminosity LHC project the injection protection system of the LHC will be upgraded in the Long Shutdown 2 (2018 - 2019) to be able to protect downstream elements against injection failures with the high brightness, high intensity HL-LHC beams.

Upgrade of the TCDQ Diluters for the LHC Beam Dump System
/ Atanasov, Miroslav G (CERN) ; Bartmann, Wolfgang (CERN) ; Borburgh, Jan (CERN) ; Boucly, Christophe (CERN) ; Bracco, Chiara (CERN) ; Gentini, Luca (CERN) ; Moles, Benjamin (CERN) ; Weterings, Wim (CERN)
The TCDQ diluters are installed as part of the LHC beam dump system to protect the Q4 quadrupole and other downstream elements during a beam dump that is not synchronised with the abort gap, or in case of erratic firing of the extraction kickers. These diluter elements installed during Run 1 were compatible with beam up to 60 % of the nominal intensity, which was insufficient for the second run of the LHC. [...]

Impedance Measurements and Simulations on the TCTP and TDI LHC Collimators
/ Biancacci, Nicolo (CERN) ; Caspers, Fritz (CERN) ; Frasciello, Oscar (LNF, Dafne Light) ; Grudiev, Alexej (CERN) ; Kuczerowski, Joseph (CERN) ; Lamas Garcia, Inigo (CERN) ; Lechner, Anton (CERN) ; Mostacci, Andrea (U. Rome La Sapienza (main)) ; Mounet, Nicolas (EPFL-ISIC, Lausanne) ; Métral, Elias (CERN) et al.
The LHC collimation system is a critical element for the safe operation of the LHC machine and is subject to continuous performance monitoring, hardware upgrade and optimization. In this work we will address the impact on impedance of the upgrades performed on the TDI injection protection collimator, where the absorber material has been changed to mitigate the device heating observed in machine operation, and on selected secondary (TCS) and tertiary (TCT) collimators, where beam position monitors (BPM) have been embedded for faster jaw alignment.

The LHC Injectors Upgrade project (LIU) has been initiated to improve the performances of the existing injector complex at CERN to match the future requirements of the HL-LHC. In this framework, the Proton Synchrotron (PS) will undergo fundamental changes for many of its main systems: the injection energy will be increased to reduce space-charge effects, the transverse damper will be improved to cope with transverse instabilities the RF systems will be upgraded to accelerate higher beam intensity and brightness.
