Conceptual Design of the HL-LHC Hollow Electron Lens Superconducting Magnet System / Foussat, Arnaud (CERN) ; Bragin, Alexey (Novosibirsk, IYF) ; Ferlin, Gerard (CERN) ; Kirby, Glyn (CERN) ; Kolehmainen, Antti (CERN) ; Nikiforov, Danila (Novosibirsk, IYF) ; Pavliuchenko, Vadim (Novosibirsk, IYF) ; Perini, Diego (CERN) ; Petrone, Carlo (CERN) ; Redaelli, Stefano (CERN) et al.
The Hollow Electron Lens (HEL) units are part of the upgrade baseline of the High-Luminosity LHC accelerator (HL-LHC) and will be installed in the machine ring at point P4 on each counter-rotating LHC proton beamline during a long shutdown in 2025-2027 at CERN. The main goal is to improve the collimation system performance by controlling beam energy loss in the beam halo. [...]

Signal Analysis for Automated Diagnostic Applied to LHC Cryogenics / Martensson, Kurt (CERN) ; Bradu, Benjamin (CERN) ; Ferlin, Gerard (CERN)
The operation of the LHC at CERN is highly dependent on its associated infrastructure to operate properly, such as its cryogenic system where many conditions must be fulfilled for superconducting magnets and RF cavities. In 2018, the LHC cryogenic system caused 172 hours of accelerator downtime (out of 5760 running hours). [...]

Chapter 9: Cryogenics for the HL-LHC / Claudet, Serge (CERN) ; Ferlin, Gerard (CERN) ; Monneret, Emmanuel (CERN) ; Perin, Antonio (CERN) ; Pirotte, Olivier (CERN) ; Sisti, M (CERN) ; Van Weelderen, Rob (CERN)
The upgrade of the cryogenics for the HL-LHC will consist of the following: - The design and installation of two new cryogenic plants at P1 and P5 for high luminosity insertions. This upgrade will be based on a new sectorization scheme aimed at separating the cooling of the magnets in these insertion regions from the arc magnets and considering the newt feedboxes and superconducting links located in underground infrastructures. - The design and installation of a new cryogenic distribution lines (QXL) at P1 and P5 in the LHC tunnel and in a new underground service galleries. - The upgrade of the existing cryogenic plant (QSRA and QURA) cooling the LHC sector 3-4 located at P4. - The cryogenic design support for superconducting devices, such as magnets, crab cavities, superconducting links, and the hollow electron lenses. Some other options such as new cryogenic circuits at P7 for the HTS links and displaced current feedboxes or a new cryoplant in P4 have been discarded..

Adaptation of the Cryogenic System Capacity for the LHC Dynamic Heat Load - Operational Experience / Brodzinski, Krzysztof (CERN) ; Bradu, Benjamin (CERN) ; Claudet, Serge (CERN) ; Delikaris, Dimitri (CERN) ; Delprat, Laurent (CERN) ; Ferlin, Gerard (CERN)
During second LHC physics operation period (Run2), between 2015 and 2018, the accelerator operation modes and beam parameters have been adapted thus allowing significantly improved integrated luminosity production. Increased energy, intensity and adapted beam operation schemes with 25 ns of inter-bunches spacing have an essential influence on the dynamic heat load generation with direct impact on the cryogenic cooling system. [...]

Beam screen cryogenic control improvements for the LHC run 2 / Bradu, Benjamin (CERN) ; Rogez, Edouard (CERN) ; Blanco Vinuela, Enrique (CERN) ; Ferlin, Gerard (CERN) ; Tovar-Gonzalez, Antonio (CERN)
This paper presents the improvements made on the cryogenic control system for the LHC beam screens. The regulation objective is to maintain an acceptable temperature range around 20 K which simultaneously ensures a good LHC beam vacuum and limits cryogenic heat loads. [...]

Compensation of Beam Induced Effects in LHC Cryogenic Systems / Bradu, Benjamin (CERN) ; Blanco Viñuela, Enrique (CERN) ; Ferlin, Gerard (CERN) ; Fernández Adiego, Borja (CERN) ; Iadarola, Giovanni (CERN) ; Plutecki, Przemyslaw (CERN) ; Rogez, Edouard (CERN) ; Tovar González, Antonio (CERN)
This paper presents the different control strategies deployed in the LHC cryogenic system in order to compensate the beam induced effects in real-time. LHC beam is inducing important heat loads along the 27 km of beam screens due to synchrotron radiations, image current and electron clouds. [...]
