Automatic Conditioning of High Voltage Pulsed Magnets / Lolliot, Christophe (CERN) ; Barnes, Michael (CERN) ; Magnin, Nicolas (CERN) ; Monier, Colin (INSA, Villeurbanne) ; Pavis, Steven (CERN)
Fast pulsed kicker magnets are used across the various accelerators of CERN complex to inject and extract the beam. These kicker magnets, powered by high voltage pulsed generators and under vacuum, are prone to electrical breakdown during the pulse. [...]

Early Fire Detection in High Power Equipment / Pavis, Steven (CERN) ; Carlier, Etienne (CERN) ; Lolliot, Christophe (CERN) ; Magnin, Nicolas (CERN)
Very early fire detection in equipment cabinets containing high power supply sources and power electronic switching devices is needed when building and tunnel fire detection systems may not be well placed to detect a fire until it is well established. Highly sensitive aspirating smoke detection systems which continuously sample the air quality inside equipment racks and give local power interlock in the event of smoke detection, are capable of cutting the source of power to these circuits at a very early stage, thereby preventing fires before they become fully established.

A Modular Approach for Accelerator Controls Components Deployment for High Power Pulsed Systems / Pavis, Steven (CERN) ; Barlow, Roger (CERN) ; Boucly, Christophe (CERN) ; Carlier, Etienne (CERN) ; Chanavat, Christophe (CERN) ; Lolliot, Christophe (CERN) ; Magnin, Nicolas (CERN) ; Van Trappen, Pieter (CERN) ; Voumard, Nicolas (CERN)
As part of the LHC Injector Upgrade (LIU) project, the controls of the PSB and PS injection kickers at CERN have been upgraded during Long Shutdown 2 (LS2) from heterogeneous home-made electronic solutions to a modular and open architecture. Despite both kickers have significantly different functionalities, topologies and operational requirements, standardized hardware and software control blocks have been used for both systems. [...]

Deployment and Commissioning of the CERN PS Injection Kicker System for Operation with 2 GeV Beams in Short Circuit Mode / Kramer, Thomas (CERN) ; Ayala Cintas, Nuria (CERN) ; Borburgh, Jan (CERN) ; Burkel, Peter (CERN) ; Carlier, Etienne (CERN) ; Ducimetière, Laurent (CERN) ; Feliciano, Luís M C (CERN) ; Ferrero Colomo, Álvaro (CERN) ; Fraser, Matthew A (CERN) ; Govertsen, Leif A (CERN) et al.
Within the framework of the LHC Injector Upgrade (LIU) project, the feasibility and design of an upgrade of the existing CERN PS proton injection kicker system have been outlined in previous publications already. This paper describes the adjustments of final design choices, testing, and deployment as well as the validation and commissioning of the new 2 GeV injection kicker system. [...]

Description and performance of track and primary-vertex reconstruction with the CMS tracker / CMS Collaboration
A description is provided of the software algorithms developed for the CMS tracker both for reconstructing charged-particle trajectories in proton-proton interactions and for using the resulting tracks to estimate the positions of the LHC luminous region and individual primary-interaction vertices. Despite the very hostile environment at the LHC, the performance obtained with these algorithms is found to be excellent. [...]

Alignment of the CMS tracker with LHC and cosmic ray data / CMS Collaboration
The central component of the CMS detector is the largest silicon tracker ever built. The precise alignment of this complex device is a formidable challenge, and only achievable with a significant extension of the technologies routinely used for tracking detectors in the past. [...]
