Dielectric, thermal and mechanical properties of insulation systems for quench heaters for the protection of superconducting magnets
/ Scheuerlein, Christian (CERN) ; Osuna, Javier (CERN) ; Vielhauer, Julia (CERN) ; De Oliveira, Rui (CERN) ; Koettig, Torsten (CERN) ; Piccin, Roland (CERN)
High dielectric strength, low thermal resistance and mechanical robustness are conflicting requirements on the insulation system between the superconductors in magnet coils and the quench heaters placed on the coil for active protection in case of a quench. To investigate possibilities to further improve the performance of quench heaters for future superconducting magnets, we have characterised polyimide, PEEK and fibre reinforced PEEK films that can be used to produce large flexibly quench heater circuits.

Advanced Composite Insulation Systems in Nb$_{3}$Sn Superconducting Magnets for Accelerators: Electrical Characterization of Laminates at Cryogenic Temperatures
/ Osuna, J (CERN) ; Piccin, R (CERN) ; Pincot, F O (CERN) ; Polvani, D (CERN ; Bologna U.) ; Scheuerlein, C (CERN)
The electrical insulation system in wind-and-react Nb3Sn superconducting magnets must be robust, such that it can sustain the mechanical stresses, high radiation doses, and thermal cycles involved in the operation of the magnets. The chosen cable insulation material, currently a thin layer of braided S2 Glass, must also withstand a high-temperature heat treatment in an inert atmosphere, required to develop the superconducting phase in the cable.

Thermomechanical properties of epoxy and wax matrix composites for superconducting magnets
/ Bertsch, Jacob (CERN) ; Scheuerlein, Christian (CERN) ; Wiker, Petter (CERN ; Norwegian U. Sci. Tech.) ; Parragh, David (CERN) ; Echtermeyer, Andreas (Norwegian U. Sci. Tech.) ; Piccin, Roland (CERN)
Thermomechanical properties of epoxy resin systems and paraffin wax for the vacuum impregnation of superconducting magnet coils have been studied at ambient and at cryogenic temperatures. Parameters for the thermomechanical modelling of isotropic pure resins and anisotropic S2 glass fibre reinforced composites, and their stress limits under uniaxial tensile, bending and shear loading have been determined..

Thermomechanical properties and irradiation induced aging of SLA and FDM 3D printed high performance polymers
/ Scheuerlein, Christian (CERN) ; Parragh, David Mate (CERN) ; Vielhauer, Julia (CERN) ; Gaarud, Anders (CERN) ; Martin, Noemie (CERN) ; Piccin, Roland (CERN)
The thermomechanical properties of 3D printed polymers for potential use in superconducting devices have been compared. The FDM printed thermoplastics PEEK and ULTEM 9085 exhibit strongly anisotropic properties, with very high mechanical strength and fracture toughness in the flat and on edge printing directions, but much lower strength and toughness in the upright position.

Future Circular Collider Feasibility Study Report Volume 2 : Accelerators, technical infrastructure and safety
/ Benedikt, M. (ed.) (CERN) ; Zimmermann, F. (CERN) ; Auchmann, B. (CERN ; PSI, Villigen) ; Bartmann, W. (CERN) ; Burnet, J.P. (CERN) ; Carli, C. (CERN) ; Chancé, A. (IRFU, Saclay) ; Craievich, P. (PSI, Villigen) ; Giovannozzi, M. (CERN) ; Grojean, C. (DESY ; Humboldt U., Berlin) et al.
In response to the 2020 Update of the European Strategy for Particle Physics, the Future Circular Collider (FCC) Feasibility Study was launched as an international collaboration hosted by CERN. The FCC ‘integrated programme’, described in this report, in a first stage consists of a highest-luminosity electron-positron collider, FCC-ee, serving as Higgs, top and electroweak factory, with a subsequent energy-frontier proton-proton collider, FCC-hh, as the second stage. The FCC-ee is designed to operate at four baseline centre-of-mass energies, corresponding to the Z pole, the WW pair production threshold, the ZH production peak, and the top/anti-top production threshold, always delivering the highest possible luminosities to four experiments.

Volume 1 of the FCC Feasibility Report presents an overview of the physics case, experimental programme, and detector concepts for the Future Circular Collider (FCC). This volume outlines how the FCC would address some of the most profound open questions in particle physics, from precision studies of the Higgs and EW bosons and of the top quark, to the exploration of physics beyond the Standard Model.
