Final design of the cryostat for the high luminosity LHC magnets
/ Ramos, D (CERN) ; Vande Craen, A (CERN) ; Prin, H (CERN) ; Leclercq, Y (CERN) ; Williams, L (CERN) ; Struik, M (CERN) ; Barlow, G (CERN) ; Riu Martinez, O (CERN) ; Wong Luis, B (CERN) ; Parma, V (CERN) et al.
The high luminosity LHC project (HL-LHC) aims at increasing proton collisions by a factor of ten whilst extending physics exploitation until 2035. Its performance will rely on new focusing quadrupoles, beam separation dipoles and corrector magnets with large apertures to be installed on both sides of the ATLAS and CMS experiments. [...]

Mechanical Consolidation of the LHC Inner Triplet Magnet Supporting System for Remote Alignment
/ Micolon, Frederic (CERN) ; Bourcey, Nicolas (CERN) ; Deschamps, Jean-Baptiste (CERN) ; Herty, Andreas (CERN) ; Le Naour, Sandrine (CERN) ; Mikkola, Tommi (CERN) ; Parma, Vittorio (CERN) ; Ramos, Delio (CERN) ; Rude, Vivien (CERN) ; Sosin, Mateusz (CERN)
Given the high radiation area and the tight alignment tolerances, the LHC inner triplet magnets were designed to be realigned remotely using motorized supporting jacks. However, during run 2 the LHC triplet realignment system started to show an unexpected behavior with erratic load variations on the magnet supporting jacks when operated [...]

Status of a European Standard for the protection of helium cryostats against excessive pressure
/ Grohmann, S (KIT, Karlsruhe, IKP ; KIT, Karlsruhe) ; Barthélémy, H (Air Liquide Head Office, Paris) ; Down, R (Rutherford) ; Ercolani, E (U. Grenoble Alpes) ; Fournel, J-L (Air Liquide, Sassenage) ; Henriques, A (CERN) ; Krichler, M (Bilfinger Noell GmbH, Wurzburg) ; Otte, W (Air Liquide Deutschland GmbH, Krefeld) ; Parma, V (CERN) ; Pengo, R (INFN, Legnaro) et al.
The overpressure protection of various types of cryogenic vessels is covered by a number
of International Standards. Helium cryostats, however, include additional components such as
superconducting magnets and cavities, electrical heaters and control valves with associated
piping, which significantly influence the potential risk. [...]

Distribution Feedbox for the Superconducting Link (SCLink) and Magnets of HL-LHC
/ Bailey, W (Southampton U.) ; Pelegrin, J (Southampton U.) ; Falorio, I (Southampton U. ; CERN) ; Leclercq, Y (CERN) ; Betemps, R (CERN) ; Parma, V (CERN) ; Ballarino, A (CERN) ; Yang, Y (Southampton U.)
The High Luminosity LHC (HL-LHC) project aims at upgrading the LHC collider to increase its luminosity by about a factor of five. The electrical connection between the magnets in the LHC tunnel and the power converters in a new transverse tunnel will be supplied by a superconducting line (SCLink), consisting of ten MgB$_2$ cables housed into a 140 metre long flexible cryostat.
