Light a candle for impregnation of superconducting magnets with wax: Thermo-mechanical behavior of an alumina-filled paraffin wax from ambient to cryogenic temperatures / Kong, Xiang (ETH, Zurich (main)) ; Van den Eijnden, Joep L (PSI, Villigen ; ETH, Zurich (main)) ; Brem, André (PSI, Villigen) ; Araujo, Douglas (PSI, Villigen) ; Auchmann, Bernhard (PSI, Villigen ; CERN) ; Tervoort, Theo A (ETH, Zurich (main))
A paraffin-wax-based system filled with sub-micrometer alumina particles is developed for use as impregnation of superconducting magnets operating at cryogenic temperatures. The addition of alumina fillers significantly enhances the thermal and cryo-mechanical performance of the wax matrix. [...]

Performance of the Cryogenic Beam Loss Monitors Developed at the LHC / Salvachua, Belen (CERN) ; Zamantzas, Christos (CERN) ; Griesmayer, Erich (IAEA, Vienna ; New Mexico State U.) ; Effinger, Ewald (CERN) ; Storey, James (CERN) ; Meyer, Jean Michel (CERN) ; Morales Vigo, Sara (CERN)
Several systems protect the superconducting magnets of the Large Hadron Collider (LHC), which operate at -271.3C. The Beam Loss Monitoring (BLM) system is critical for detecting lost particles around the machine and reacting on their quantity and associated energy. [...]

Photon stimulated desorption from cryogenic surfaces of high temperature superconductor and amorphous carbon thin films / Tanimoto, Yasunori (KEK, Tsukuba) ; Jin, Xiuguang (KEK, Tsukuba) ; Nogami, Takashi (KEK, Tsukuba) ; Calatroni, Sergio (CERN) ; Kersevan, Roberto (CERN) ; Ady, Marton (CERN) ; Pont, Montserrat (CELLS - ALBA, LLS) ; Traver Ramos, Oriol (CELLS - ALBA, LLS) ; Puig, Teresa (Unlisted, ES) ; Gutierrez, Joffre (Unlisted, ES) et al.
High Temperature Superconductor (HTS) and amorphous Carbon (a-C) thin films, and their combination, are being considered as possible surface coatings for the FCC-hh beam screen (BS) with the aims of reduction of the resistive wall impedance and mitigation of the electron cloud. Along with these required properties, i.e., the high electron conductivity and low secondary electron yield, the Photon Stimulated Desorption (PSD) yield is one of the most essential characteristics in the design and operation of the FCC-hh vacuum systems.

Application of distributed temperature sensor for fire and cryogenic leak detection in accelerator tunnels / Dole, Michael (CERN) ; Di Francesca, Diego (CERN) ; Nissen, Henrik (CERN) ; Blanc, Jeremy (CERN) ; Bremer, Johan (CERN) ; FERNANDEZ, Julien (CERN) ; Dufay-Chanat, Laetitia (CERN) ; Contini, Lorenzo (CERN) ; Van de veire, Matthias (CERN) ; Rios, Oriol (CERN) et al.
High-energy accelerators like CERN’s Large Hadron Collider (LHC) present hazards characterized by temperature variations such as cryogenic leak or fire. Considering that LHC tunnels are large, underground, and radioactive areas, alternatives to traditional systems are explored to improve hazard detection. [...]

The third long shutdown (LS3) of the CERN accelerator complex / Tock, Jean-Philippe (CERN) ; Herty, Andreas (CERN) ; Borglund, Ayla (CERN) ; Duchemin, Charlotte (CERN) ; Bedel, Cyrille (CERN) ; Dos Santos Pedrosa, Fernando (CERN) ; Riddone, Germana (CERN) ; Etheridge, John (CERN) ; FERNANDEZ, Julien (CERN) ; Bernardini, Marzia (CERN) et al.
TThe Large Hadron Collider (LHC) operation began in 2008. Its superconducting equipment requires a cool-down/warm-up cycle lasting several months to access some key elements such as superconducting magnets, making annual shutdowns impractical and obliged for a change in programmed stops paradigm. [...]

Consolidation of personnel safety systems at CERN / Evrard, Sebastien (CERN) ; Suwalska, Anna (CERN) ; Morand, Boris (CERN) ; Raffourt, Denis (CERN) ; Sanchez-Corral Mena, Eva (CERN) ; Havart, Frederic (CERN) ; Olivet Dessent, German (CERN) ; Godineau, Gregory (CERN) ; Krautsztrung, Iga (CERN) ; FERNANDEZ, Julien (CERN) et al.
Personnel Safety Systems provide prevention and mitigation barriers to protect personnel, users, equipment, and the environment against the risks associated with the operation of the CERN Accelerators and Experiments, such as Radiation, Fire, Gas and Oxygen Deficiency Hazards. Due to the obsolescence or ageing of technology, evolutions of the facility and the Safety rules, it is now time to consolidate existing safety systems to prepare the CERN complex for the coming decades.
