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. [...]

Summary of the Post-Long Shutdown 2 LHC Hardware Commissioning Campaign / Apollonio, Andrea (CERN) ; Andreassen, Odd (CERN) ; Antoine, Alain (CERN) ; Argyropoulos, Theodoros (CERN) ; Bastos, Miguel (CERN) ; Bednarek, Mateusz (CERN) ; Bordini, Bernardo (CERN) ; Brodzinski, Krzysztof (CERN) ; Calia, Andrea (CERN) ; Charifoulline, Zinour (CERN) et al.
In this contribution we provide a summary of the LHC hardware commissioning campaign following the second CERN Long Shutdown (LS2), initially targeting the nominal LHC energy of 7 TeV. A summary of the test procedures and tools used for testing the LHC superconducting circuits is given, together with statistics on the successful test execution. [...]

Interlock System Upgrades at the CERN Accelerator Complex During Long Shutdown 2 / Uythoven, Jan (CERN) ; Antoine, Alain (CERN) ; Martin, Christophe (CERN) ; Mirana Fontan, Adrian (CERN) ; Mompo, Richard (CERN) ; Romera Ramírez, Iván (CERN) ; Secondo, Raffaello (CERN)
The CERN accelerator complex stopped operation at the end of 2018 for the Long Shutdown 2 (LS2), allowing for the LHC Injector Upgrade program (LIU) and consolidation work to be accomplished. A gradual restart of the different accelerators is ongoing in 2021, culminating with the LHC foreseen to be back in operation early 2022. [...]

Operational performance of the machine protection systems of the Large Hadron Collider during Run 2 and lessons learnt for the LIU/HL-LHC era / Zerlauth, Markus (CERN) ; Antoine, Alain (CERN) ; Bartmann, Wolfgang (CERN) ; Bracco, Chiara (CERN) ; Carlier, Etienne (CERN) ; Charifoulline, Zinour (CERN) ; Denz, Reiner (CERN) ; Goddard, Brennan (CERN) ; Lechner, Anton (CERN) ; Magnin, Nicolas (CERN) et al.
The Large Hadron Collider (LHC) has successfully completed its second operational run in December 2018. To allow for the completion of the diverse physics program at 6.5 TeV, the machine has been routinely operating with stored beam energies up to 300 MJ per beam during high intensity proton runs as well as being frequently reconfigured to allow for special physics runs and important machine development studies.

Integration of PLC and PXI control systems / Antoine, Alain (CERN) ; Boucly, Christophe (CERN) ; Gharsa, Thierry (CERN)
Engineers are often challenged with the need to integrate several technologies to find optimal solutions when designing new control architectures. Generally, the technical solutions chosen require the combination of various industrial products such as PXI systems for applications requiring fast acquisition, analysis and reaction times, while PLCs are commonly used for their reliability and their ability to withstand industrial environments. [...]

Upgrade of the Trigger Synchronisation and Distribution System of the Beam Dumping System of the Large Hadron Collider / Magnin, Nicolas (CERN) ; Antoine, Alain (CERN) ; Carlier, Etienne (CERN) ; Chareyre, Vincent (CERN) ; Gabourin, Stéphane (CERN) ; Patsouli, Anastasia (CERN) ; Voumard, Nicolas (CERN)
Various upgrades were performed on the Large Hadron Collider (LHC) Beam Dumping System (LBDS) during Long Shutdown 1 (LS1) at CERN, in particular to the Trigger Synchronisation and Distribution System (TSDS): A redundant direct connection from the LHC Beam Interlock System to the re-trigger lines of the LBDS was implemented, a fully redundant powering architecture was set up, and new Trigger Synchronisation Unit cards were deployed over two separate crates instead of one. These hardware changes implied the adaptation of the State Control and Surveillance System and an improvement of the monitoring and diagnosis systems, like the various Internal Post Operation Check (IPOC) systems that ensure that, after every beam dump event, the LBDS worked as expected and is 'as good as new' for the next LHC beam.
