/ Wiesner, Christoph (CERN) ; Bartmann, Wolfgang (CERN) ; Bracco, Chiara (CERN) ; Carlier, Etienne (CERN) ; Ducimetière, Laurent (CERN) ; Frankl, Matthias (CERN) ; Fraser, Matthew (CERN) ; Goddard, Brennan (CERN) ; Kramer, Thomas (CERN) ; Lechner, Anton (CERN) et al.
The High Luminosity Large Hadron Collider (HL-LHC) project will increase the total beam intensity in the LHC by nearly a factor of two. Analysis and follow-up of recent operational issues as well as dedicated studies of the LHC Beam Dump System (LBDS) have been carried out to ensure the safe operation with HL-LHC parameters and to decide on possible hardware upgrades to meet the HL-LHC requirements.

Asynchronous Beam Dump Tests at LHC
/ Wiesner, Christoph (CERN) ; Bartmann, Wolfgang (CERN) ; Bracco, Chiara (CERN) ; Carlier, Etienne (CERN) ; Ducimetière, Laurent (CERN) ; Frankl, Matthias (CERN) ; Fraser, Matthew (CERN) ; Goddard, Brennan (CERN) ; Heßler, Christoph (CERN) ; Kramer, Thomas (CERN) et al.
The detailed understanding of the beam-loss pattern in case of an asynchronous beam dump is essential for the safe operation of the future High Luminosity LHC (HL-LHC) with nearly twice the nominal LHC beam intensity, leading to correspondingly higher energy deposition on the protection elements. An asynchronous beam dump is provoked when the rise time of the extraction kickers is not synchronized to the 3 us long particle-free abort gap. [...]

Injection and Dump Systems for a 13.5 TeV Hadron Synchrotron HE-LHC

One option for a future circular collider at CERN is to build a 13.5 TeV hadron synchrotron, or High Energy LHC (HE-LHC) in the LHC tunnel. Injection and dump systems will have to be upgraded to cope with the higher beam rigidity and increased damage potential of the beam. [...]

Upgrade of the Dilution System for HL-LHC

The LHC Beam Dump System is one of the most critical systems for reliable and safe operation of the LHC. A dedicated dilution system is required to sweep the beam over the front face of the graphite dump core in order to reduce the deposited energy density. [...]

The Trigger Synchronization and Distribution System (TSDS) is a core part of the LHC Beam Dump System (LBDS). It comprises redundant Re-Trigger Lines (RTLs) that allow fast re-triggering of all high-voltage pulsed generators in case one self-triggers, resulting in a so-called asynchronous dump. [...]

The Future Circular Collider (FCC) study considers several injector scenarios for FCC-hh, the proposed 100~TeV centre of mass hadron collider located at CERN. The investigated options include amongst others to use the LHC at 3.3~TeV or a superconducting SPS at 1.3~TeV as a High Energy Booster (HEB). [...]
