	The SPS high energy internal dump (TIDVG) is designed to receive beam dumps from 10².2 to 450 GeV. The absorbing core is composed of 2.5m graphite, followed by 1m of aluminium, then 0.5m of copper and finally 0.3m of tungsten, all of which is surrounded by a water cooled copper jacket. An inspection during Long Shutdown 1 revealed significant beam induced damage to the Al section of the dump block. Temperature sensors were installed to monitor the new dump replacing the damaged one. This paper summarises the correlation between the temperature measured as a function of the energy deposited and the same temperatures computed in a numerical model combining FLUKA and ANSYS simulations. The goal of this study is the assessment of the thermal contact quality between the beam absorbing blocks and the copper jacket, by analysing the cooling times observed from the measurements and from the thermo-mechanical simulations. This paper presents an improved method to estimate the efficiency and long term reliability of the cooling of this type of design, with the view of optimising the performance of future dump versions.

TUPTY028	Collimator Layouts for HL-LHC in the Experimental Insertions	2064
	R. Bruce, F. Cerutti, L.S. Esposito, J.M. Jowett, A. Lechner, E. Quaranta, S. Redaelli, M. Schaumann, E. Skordis, G.E. Steele CERN, Geneva, Switzerland H. Garcia Morales, R. Kwee-Hinzmann JAI, Egham, Surrey, United Kingdom
	This paper presents the layout of collimators for HL-LHC in the experimental insertions. On the incoming beam, we propose to install additional tertiary collimators to protect potential new aperture bottlenecks in cells 4 and 5, which in addition reduce the experimental background. For the outgoing beam, the layout of the present LHC with three physics debris absorbers gives sufficient protection for high-luminosity proton operation. However, collisional processes for heavy ions cause localized beam losses with the potential to quench magnets. To alleviate these losses, an installation of dispersion suppressor collimators is proposed.

TUPTY048	Changes to the Transfer Line Collimation System for the High-Luminosity LHC Beams	2124
	V. Kain, O. Aberle, C. Bracco, M.A. Fraser, F. Galleazzi, A. Kosmicki, F.L. Maciariello, M. Meddahi, F.-X. Nuiry, G.E. Steele, F.M. Velotti CERN, Geneva, Switzerland E. Gianfelice-Wendt Fermilab, Batavia, Illinois, USA
	The current LHC transfer line collimation system will not be able to provide enough protection for the high brightness beams in the high-luminosity LHC era. The new collimation system will have to attenuate more and be more robust than its predecessor. The active jaw length of the new transfer line collimators will therefore be 2.1 m instead of currently 1.2 m. The transfer line optics will have to be adjusted for the new collimator locations and larger beta functions at the collimators for absorber robustness reasons. In this paper the new design of the transfer line collimation system will be presented with its implications on transfer line optics and powering, maintainability, protection of transfer line magnets in case of beam loss on a collimator and protection of the LHC aperture

TUPTY049	Protection of Superconducting Magnets in Case of Accidental Beam Losses during HL-LHC Injection	2128

	Funding: Research supported by the High Luminosity LHC project. The LHC injection regions accommodate a system of beam-intercepting devices which protect superconducting magnets and other accelerator components in case of mis-steered injected beam or accidentally kicked stored beam, e.g. due to injection kicker or timing malfunctions. The brightness and intensity increase required by the High Luminosity (HL) upgrade of the LHC necessitates a redesign of some devices to improve their robustness and to reduce the leakage of secondary particle showers to downstream magnets. In this paper, we review possible failure scenarios and we quantify the energy deposition in superconducting coils by means of FLUKA shower calculations. Conceptual design studies for the new protection system are presented, with the main focus on the primary injection protection absorber (TDI) and the adjacent mask (TCDD).

TUPTY050	Considerations for the Beam Dump System of a 100 TeV Centre-of-mass FCC hh Collider	2132

	A 100 TeV centre-of-mass energy frontier proton collider in a new tunnel of 80–100 km circumference is a central part of CERN’s Future Circular Colliders (FCC) design study. One of the major challenges for such a machine will be the beam dump system, which for each ring will have to reliably abort proton beams with stored energies in the range of 8 Gigajoule, more than an order of magnitude higher than planned for HL-LHC. The transverse proton beam energy densities are even more extreme, a factor of 100 above that of the presently operating LHC. The requirements for the beam dump subsystems are outlined, and the present technological limitations are described. First concepts for the beam dump system are presented and the feasibility is discussed, highlighting in particular the areas in which major technological progress will be needed. The potential implications on the overall machine and other key subsystems are described, including constraints on filling patterns, interlocking, beam intercepting devices and insertion design.

	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. The upgraded LHC injection protection system will consist of a segmented injection protection absorber TDIS, and auxiliary collimators and masks. The layout modifications are described, and the machine element protection and absorber jaw robustness studies are presented for the new systems.

WEPMN068	Upgrade of the CERN SPS Extraction Protection Elements TPS	3083
	J. Borburgh, B. Balhan, M.J. Barnes, C. Baud, M.A. Fraser, V. Kain, F.L. Maciariello, G.E. Steele, F.M. Velotti CERN, Geneva, Switzerland
	In 2006 the protection devices upstream of the septa in both extraction channels of the CERN SPS to the LHC were installed. Since then, new beam parameters have been proposed for the SPS beam towards the LHC in the framework of the LIU project. The mechanical parameters and assumptions on which these protection devices presently have been based, need validation before the new upgraded versions can be designed and constructed. The paper describes the design assumptions for the present protection device and the testing program for the TPSG4 at HiRadMat to validate them. Finally the requirements and the options to upgrade both extraction protection elements in the SPS are described.

	The high energy beam dump in the SPS has to deal with beams from 10⁵ to 450 GeV/c and intensities of up to 4 ×10¹³ protons. An inspection during the last shutdown revealed significant damage to the Al section of the dump block. This paper summarizes the results of the analysis revealing the most likely cause of the damage to the beam dump.

	The CERN Super Proton Synchrotron (SPS) presently uses an internal beam dump system with two separate blocks to cleanly dispose of low and high energy beams. In view of the increased beam power and brightness needed for the LHC Injector Upgrade project for High Luminosity LHC (HL-LHC), the performance of this internal beam dump system has been reviewed for future operation. Different possible upgrades of the beam dumping system have been investigated. The initially considered solution for the SPS Beam Dump System is to design a new, dedicated external system, with a dump block in a shielded cavern separated from the machine ring. Unfortunately this solution is not feasible with the present technology. In this paper, the design requirements and the possible solutions are investigated, including considering a new internal beam dump in the Long Straight Section 5 (LSS5).

	As part of the LHC Injectors Upgrade Project (LIU) the injection system into the SPS will be upgraded for the use with ions. The changes will include the addition of a Pulse Forming Line parallel to the existing PFN to power the kicker magnets MKP-S. With the PFL a reduced magnetic field rise time of 100 ns should be reached. The missing deflection strength will be given by two new septum magnets MSI-V, to be installed between the existing septum MSI and the kickers MKP-S. A dedicated ion dump will be installed downstream of the injection elements. The parameter lists of the elements and studies concerning emittance blow-up coming from the injection system are presented. The feasibility of the 100 ns kicker rise time and the small ripple of the septum power converter are presented. Material studies of the ion dump are presented together with the radiation impact.
