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. [...]

An international collaboration of research teams from CEA (France), CERN (Switzerland), INFN/LNL (Italy), HZB and USI (Germany), IEE (Slovakia), RTU (Latvia) and STFC/DL (UK), are working together on better understanding of how to improve the properties of superconducting thin films (ScTF) for RF cavities. The collaboration has been formed as WP15 in the H2020 ARIES project funded by EC. [...]

Accel. Sci. Tech.) ; Medvids, Arturs (Riga Tech. U.) ; Onufrijevs, Pavels (Riga Tech. U.) et al.
The production of superconducting coatings for radio frequency (RF) cavities has been developed over several decades. It is widely accepted that for any further improvement in cavity RF performance, innovation is needed and one may have to turn to other forms of Nb and other superconducting materials. [...]

The HL-LHC Project Gets Ready for Its Deployment
/ Zerlauth, Markus (CERN) ; Brüning, Oliver (CERN) ; Di Girolamo, Beniamino (CERN) ; Fessia, Paolo (CERN) ; Gaignant, Christelle (CERN) ; Garcia Gavela, Hector (CERN) ; Maclean, Ewen (CERN) ; Modena, Michele (CERN) ; Otto, Thomas (CERN) ; Tavian, Laurent (CERN) et al.
Following the successful completion of the second long shutdown (LS2), the Large Hadron Collider (LHC) is preparing for its final operational run before the majority of the High Luminosity Upgrade (HL-LHC) will be installed during the third Long Shutdown starting in 2026. The HL-LHC upgrade will enable a further tenfold increase in integrated luminosity delivered to the ATLAS and CMS experiments, starting by an upgrade of the machine protection, collimation and shielding systems in LS2, and followed by the deployment of novel key technologies, including Nb₃Sn based insertion region magnets, cold powering by MgB₂ superconducting links and integration of Nb crab-cavities to compensate the effects of a larger crossing angle.

Quench localisation in SRF cavity tests with transition edge sensors

Transition edge sensors (TES) have recently been developed at CERN as second sound detectors for quench localisation on superconducting radio frequency (SRF) cavities. After validation of the concept of heat source localisation by TES in the laboratory, TES have been implemented as a diagnostic tool in SRF vertical testing cryostats at CERN SM18 facility. [...]
