Project management structures, processes, and tools for the HL-LHC project
/ Vandoni, Giovanna (CERN) ; Brüning, Oliver (CERN) ; Di Girolamo, Beniamino (CERN) ; Fessia, Paolo (CERN) ; Garcia Gavela, Hector (CERN) ; Jensen, Lars (CERN) ; Modena, Michele (CERN) ; Noels, Cecile (CERN) ; Tavian, Laurent (CERN) ; Zerlauth, Markus (CERN)
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. [...]

Electromagnetic Modelling of Kicker Magnets to Derive Equivalent Circuits
/ Barnes, Michael J (CERN) ; Bjorkqvist, Oskar (CERN) ; Jensen, Lars (CERN ; Aarhus U.) ; Nielsen, Oliver (CERN ; Aarhus U.)
An equivalent circuit model of a kicker magnet system is an invaluable tool for predicting the performance, studying possible modifications and for helping to diagnose faults. The frequency content of pulses associated with a ferrite loaded transmission line kicker magnet generally extend up to a few tens of MHz: hence, it is feasible to accurately model such a kicker magnet using lumped elements. [...]

Measuring beam size with the LHC Beam Gas Vertex detector
/ Würkner, Benedikt (CERN) ; Alexopoulos, Andreas (CERN) ; Barschel, Colin (CERN) ; Bay, Aurelio (Ecole Polytechnique, Lausanne) ; Blanc, Frederic (Ecole Polytechnique, Lausanne) ; Bravin, Enrico (CERN) ; Bregliozzi, Giuseppe (CERN) ; Chritin, Nicolas (CERN) ; Dehning, Bernd (CERN) ; Ferro-Luzzi, Massimiliano (CERN) et al.
The Beam Gas Vertex detector (BGV) is an innovative beam profile monitor being developed as part of the High Luminosity LHC (HL-LHC) project at CERN. The goal is to continually measure the transverse beam size by reconstructing tracks originating from beam-gas interactions using high precision tracking detectors. [...]
