Hardware Commissioning of the HL-LHC Inner Triplet String Facility at CERN: Individual System and Short Circuit Tests
/ Yammine, Samer (CERN) ; Antoine, Alain (CERN) ; Onufrena, Aleksandra (CERN) ; Perin, Antonio (CERN) ; Panev, Bozhidar Ivanov (CERN) ; Bozzini, Davide (CERN) ; Coulot, Emilien (CERN) ; Thiesen, Hugues (CERN) ; Zerlauth, Markus (CERN) ; Bajko, Marta (CERN) et al.
The goal of the High Luminosity-Large Hadron Collider (HL-LHC) Inner Triplet (IT) String test, is to validate the assembly and connection procedures and tools required for its construction, to assess the collective behavior of the superconducting magnet chain in conditions as close as possible to those of their operation in the HL-LHC and to provide a training opportunity for the equipment teams for their work in the LHC tunnel. The IT String includes the systems required for operation at nominal conditions, such as the cryogenics, powering and quench protection systems. [...]

Chapter 9: Circuit Layout, Powering and Protection
/ Mateos, F Rodríguez (CERN) ; Rosa, T D Catalão Da (Unlisted, CH) ; Cámara, F Menéndez (Unlisted, CH) ; Yammine, S (CERN) ; Zerlauth, M (CERN)
The HL-LHC upgrade will impose changes to the magnet circuits in Points 1, 5 and 7 with respect to the present LHC configuration. This chapter describes those changes and describes the powering characteristics and protection strategies applicable to the new magnet circuits. [...]

Chapter 12: Machine Protection in the High Luminosity LHC
/ Apollonio, A ; Bélanger, P (CERN) ; Carrillo, D (CERN) ; Denz, R (CERN) ; Mateos, F Rodriguez (CERN) ; Panev, B (CERN) ; Siemko, A (CERN) ; Uythoven, J (CERN) ; Verweij, A (CERN) ; Wollmann, D (CERN) et al.
In the high luminosity era of the LHC, the energy stored in the two beams will nearly double as compared with the design value of the current LHC and the beta functions will significantly increase in critical locations. In addition, novel equipment like Nb3Sn based superconducting magnets, crab cavities, hollow e-lenses and others will be installed. [...]

HL-LHC IT STRING: Status and Perspectives
/ Bajko, M (CERN) ; Baglin, V (CERN) ; Ballarino, A (CERN) ; Bednarek, M J (CERN) ; Bertolasi, S (CERN) ; Bertone, C (CERN) ; Blanchard, S (CERN) ; Bozzini, D (CERN) ; Coulot, E (CERN) ; Coupat, C (CERN) et al.
The HL-LHC IT STRING, an integrated test stand for the major components of the HL-LHC Inner Triplet (IT) zone, is in its construction phase in a surface building at CERN. The main motivation is to study and validate the collective behavior of the different systems: magnets, circuit protection, cryogenics for magnets and superconducting link, magnet powering, vacuum, alignment, and interconnections between magnets and superconducting link.

At its restart after a major shutdown in 2029, the LHC will see its interaction regions upgraded by the installation of the HL-LHC equipment, with new Nb3Sn triplets and cold powering system, crab-cavities for crossing angle compensation and luminosity levelling, an upgraded collimation system, and fully remote alignment for the final focusing region. In the following operational runs, the LHC will aim at a tenfold increase of the integrated luminosity compared to the original design. [...]

The HL-LHC project covers the upgrade of the LHC, aiming at collecting an integrated luminosity of 3000 fb-1 equal to a 10-fold increase of the nominal LHC performance. Approved in 2016 for a 950 MCHF budget, the project is shaped by 19 work-packages, covering all expertise areas, from beam dynamics to technical infrastructures. [...]
