Design of a Very Low Energy Beamline for NA61/SHINE / Mussolini, Carlo Alberto (CERN ; JAI, UK) ; Burrows, Philip N (JAI, UK) ; Charitonidis, Nikolaos (CERN) ; Nagai, Yoshikazu (U. Colorado, Boulder) ; Zimmerman, Eric D (U. Colorado, Boulder)
A new, low-energy beamline branch is currently under consideration for the H₂ beamline at the CERN North Area. This new branch would extend the capabilities of the current infrastructure enabling the study of particles in the very low, 1-13 GeV/c, momentum range. [...]

Beam Induced Power Deposition in CERN SPS Injection Kickers / Barnes, Michael J (CERN) ; Bjorkqvist, Oskar (CERN) ; Kodama, Kota (CERN ; KEK, Tsukuba)
The SPS injection kicker magnets (MKP) were developed in the 1970’s, before beam power deposition was considered an issue and before any advanced tools for analysing beam coupling impedance were available in their current form. These magnets are very lossy from a beam impedance perspective, and the beam induced power deposition is highly non-uniform. [...]

Modernisation of the Toolchain and Continuous Integration of Front-End Computer Software at CERN / Mantion, Pierre (CERN) ; Deghaye, Stephane (CERN) ; Fiszer, Lukasz (CERN) ; Irannejad, Farhad (CERN) ; Lauener, Joel (CERN) ; Voelkle, Martin (CERN)
Building C++ software for low-level computers requires carefully tested frameworks and libraries. The major difficulties in building C++ software are to ensure that the artifacts are compatible with the target system’s (OS, Application Binary Interface), and to ensure that transitive dependent libraries are compatible when linked together.

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. [...]

CERN SPS Sprinkler System: A Customized Industrial Solution for a Non-Conventional Site / Suwalska, Anna (CERN) ; Arnalich, Arturo (CERN) ; Deperraz, Florian (CERN) ; Munoz Codoceo, Miriam (CERN) ; Ninin, Pierre (CERN)
Until 2018, the limited firefighting means in the SPS complex largely exposed it to the consequences of self-ignition or accidental fire. In 2015 the SPS Fire Safety project was launched with the objective of improving life safety and property protection by deploying a whole set of automatic actions to protect SPS in case of fire outbreak.

Studies for Mitigating Flashover of CERN-LHC Dilution Kicker Magnets / Loebner, Alina M (CERN) ; Barnes, Michael J (CERN) ; Bartmann, Wolfgang (CERN) ; Bracco, Chiara (CERN) ; Ducimetière, Laurent (CERN) ; Namora, Vasco (CERN) ; Senaj, Viliam (CERN)
The LHC beam dump system is used for extracting beam from the LHC and, as such, is a safety critical system whose proper functionality must be assured. Dilution kicker magnets (MKBs) sweep the extracted beam over the cross-sectional area of a dump block as the energy density would otherwise be too high and damage the block. [...]

Applying Model Checking to Highly-Configurable Safety Critical Software: The SPS-PPS PLC Program / Fernández Adiego, Borja (CERN) ; Blanco Viñuela, Enrique (CERN) ; Havart, Frederic (CERN) ; Ladzinski, Tomasz (CERN) ; Lopez-Miguel, Ignacio D (CERN) ; Tournier, Jean-Charles (CERN)
An important aspect of many particle accelerators is the constant evolution and frequent configuration changes that are needed to perform the experiments they are designed for. This often leads to the design of configurable software that can absorb these changes and perform the required control and protection actions. [...]

A semi-empirical model for preheater design to trigger CO$_2$ boiling for detector cooling / Baldinelli, G (INFN, Perugia ; U. Perugia (main)) ; French, T (CERN) ; Bianchi, F (INFN, Perugia ; Perugia U.) ; Daguin, J (CERN) ; Onnela, A (CERN) ; Tropea, P (CERN)
The fluid properties of CO$_2$ make it an ideal medium for the cooling of tracking detectors in experiments at particle accelerators. Detectors such as the Compact Muon Solenoid Outer Tracker at CERN will be cooled to a nominal temperature of -35 °C with CO$_2$ cooling to ensure the longevity of the silicon sensors. [...]

Development of an Automated High Temperature Superconductor Coil Winding Machine at CERN / Reymond, Hubert (CERN) ; Dam, Magnus (CERN) ; Felice, Helene (CERN) ; Haziot, Ariel (CERN) ; Jankowski, Patryk (CERN) ; Koziol, Piotr (CERN) ; Nes, Thomas (CERN) ; Pincot, Francois (CERN) ; Richter, Sebastian (CERN)
Within the framework of technology studies on future accelerators, CERN has initiated a five-years R&D; project aimed at the evaluation of the REBCO (Rare Earth Barium Copper Oxide) High Temperature Superconductors (HTS). The study covers a number of areas from material science to electromechanical properties. [...]
