Comparison of floating and thermalized multilayer insulation systems at low boundary temperature
/ Ferlin, G ; Jenninger, B ; Lebrun, P ; Peón-Hernández, G ; Riddone, G ; Szeless, Balázs
The Large Hadron Collider (LHC) is 26.7 km circumference particle collider using high-field superconducting magnets operating in superfluid helium. An efficient and robust thermal insulation system is therefore required to minimize the residual heat in leak to the large surface area at 1.9 K constituted by the stainless steel wall of the helium enclosure.

Refrigeration System for the ATLAS Experiment
/ Haug, F ; Dauvergne, J P ; Passardi, Giorgio ; Cragg, D ; Curé, C ; Pailler, P ; Mayri, C ; Yamamoto, A
The proposed ATLAS detector for the 27 km circumference LHC collider is of unprecedented size and complexity. The magnet configuration is based on an inner superconducting solenoid and large superconducting air-core toroids (barrel and two end-caps) each made of eight coils symmetrically arranged outside the calorimetry.

Power Test Results of the First LHC Second Generation Superconducting Single Aperture 1m Long Dipole Models
/ Kirby, G A ; Ostler, J M ; Perini, D ; Siegel, N ; Siemko, A ; Tommasini, D ; Walckiers, L
Within the LHC magnet research and development programme, a series of single aperture 1m long models of second generation are presently being built and tested at CERN. The main features of these magnets are: five-block, two layer coils wound from 15mm wide graded NbTi cables, enlarged 56mm aperture and all-polyimide insulation. [...]

A cryogenic axial-centrifugal compressor for superfluid helium refrigeration
/ Decker, L ; Löhlein, K ; Schustr, P ; Vins, M ; Brunovsky, I ; Lebrun, P ; Tavian, L
CERN's new project, the Large Hadron Collider (LHC), will use superfluid helium as coolant for its high-field superconducting magnets and therefore require large capacity refrigeration at 1.8 K. This may only be achieved by subatmospheric compression of gaseous helium at cryogenic temperature. [...]

Cryogenic operation and testing of the extended LHC prototype magnet string
/ Bézaguet, Alain-Arthur ; Casas-Cubillos, J ; Guinaudeau, H ; Hilbert, B ; Lebrun, P ; Serio, L ; Suraci, A ; Van Weelderen, R
After the assembly, commissioning and successful first operation of a full-scale superconducting magnet string, and as a new prototype dipole magnet was added to approach final configuration, the cryogenic system has been slightly modified to allow the verification of the performance of the superfluid helium cooling loop in counter-current two-phase flow. At the same time the control system strategies have been updated and only two quench relief valves have been installed, one at each end of the string. [...]

Characterisation of net type thermal insulators at 1.8 K low boundary temperature
/ Peón-Hernández, G ; Jenninger, B ; Szeless, Balázs
The Large Hadron Collider's superconducting magnets are cooled by superfluid helium at 1.8 K and housed in cryostats that minimise the heat inleak to this temperature level by extracting heat at 70 and 5 K. In the first generation of prototype cryostats, the radiative heat to the 1.8 K temperature level accounted for 70 % of the total heat inleak. [...]
