Magnets are at the core of both circular and linear accelerators. The main function of a magnet is to guide the charged particle beam by virtue of the Lorentz force, given by the following expression:where q is the electrical charge of the particle, v its velocity, and B the magnetic field induction.

Does One Need a 4.5 K Screen in Cryostats of Superconducting Accelerator Devices Operating in Superfluid Helium? Lessons from the LHC / Lebrun, Ph ; Parma, V ; Tavian, L
Superfluid helium is increasingly used as a coolant for superconducting devices in particle accelerators: the lower temperature enhances the performance of superconductors in high-field magnets and reduces BCS losses in RF acceleration cavities, while the excellent transport properties of superfluid helium can be put to work in efficient distributed cooling systems.

Beyond the Large Hadron Collider: a first look at cryogenics for CERN future circular colliders / Lebrun, Ph (CERN) ; Tavian, L (CERN)
Following the first experimental discoveries at the Large Hadron Collider (LHC) and the recent update of the European strategy in particle physics, CERN has undertaken an international study of possible future circular colliders beyond the LHC. The study, conducted with the collaborative participation of interested institutes world-wide, considers several options for very high energy hadron-hadron, electron-positron and hadron-electron colliders to be installed in a quasi-circular underground tunnel in the Geneva basin, with a circumference of 80 km to 100 km.

Cryogénie hélium et efficacité énergétique: L'expérience du LHC au CERN / Claudet, S (CERN) ; Lebrun, Ph (CERN) ; Tavian, L (CERN)
Résumé La supraconductivité et la cryogénie hélium associée sont devenues des technologies clés des grands équipements de recherche en physique, et en particulier des accélérateurs de particules. Le coût thermodynamique du fonctionnement à basse température impose à leurs systèmes cryogéniques une haute efficacité énergétique dans la gestion des charges thermiques, la distribution des fluides et la production de froid, obtenue par une approche intégrée couvrant toutes les phases du projet, de la conception préliminaire jusqu'à l'exploitation.

CLIC Energy Scans / Schulte, D (CERN) ; Adli, E (Oslo U. ; CERN) ; Corsini, R (CERN) ; Dalena, B (CERN) ; Delahaye, JP (CERN) ; Doebert, S (CERN) ; Geschonke, G (CERN) ; Grudiev, A (CERN) ; Jeanneret, B (CERN) ; Jensen, E (CERN) et al.
The physics experiments at CLIC will require that the machine scans lower than nominal centre-of-mass energy. We present different options to achieve this and discuss the implications for luminosity and the machine design..

Exergy Analysis of the Cryogenic Helium Distribution System for the Large Hadron Collider (LHC) / Claudet, S (CERN) ; Lebrun, Ph (CERN) ; Tavian, L (CERN) ; Wagner, U (CERN)
The Large Hadron Collider (LHC) at CERN features the world’s largest helium cryogenic system, spreading over the 26.7 km circumference of the superconducting accelerator. With a total equivalent capacity of 145 kW at 4.5 K including 18 kW at 1.8 K, the LHC refrigerators produce an unprecedented exergetic load, which must be distributed efficiently to the magnets in the tunnel over the 3.3 km length of each of the eight independent sectors of the machine.
