The potential of cryogenic helium flows for studying high-Reynolds number turbulence in the laboratory has been recognised for a long time and implemented in several small-scale hydrodynamic experiments. With its large superconducting particle accelerators and detector magnets, CERN, the European Laboratory for Particle Physics, has become a major world center in helium cryogenics, with several large helium refrigerators having capacities up to 18 kW @ 4.5 K.

Towards Cost-To-Performance Optimisation of Large Superfluid Helium Refrigeration Systems / Claudet, S ; Lebrun, P ; Tavian, L
The field range of superconducting devices may be extended by lowering their operating temperature, using superfluid helium refrigeration systems which have to deliver working pressures down to 1.6 kPa. The corresponding pressure ratio can be produced by integral cold compression or using a combination of cold compressors in series together with "warm" compressors at room temperature. [...]

Superfluid helium : physics and applications / Vinen, W F ; Lebrun, Philippe
The behaviour of liquid helium is dominated by quantum effects, which give rise to superfluidity at low temperatures. An account will be given of the observed properties of the superfluid phase of liquid 4He, and of the way in which these properties can be described by a two-fluid model, supplemented by the requirement that motion of the superfluid component be irrotational with a hydrodynamic circulation that is quantized in units of h/m4.

Advanced Superconducting Technology for Global Science : The Large Hadron Collider at CERN / Lebrun, P
The Large Hadron Collider (LHC), presently in construction at CERN, the European Organisation for Nuclear Research near Geneva (Switzerland), will be, upon its completion in 2005 and for the next twenty years, the most advanced research instrument of the world's high-energy physics community, providing access to the energy frontier above 1 TeV per elementary constituent. Re-using the 26.7-km circumference tunnel and infrastructure of the past LEP electron-positon collider, operated until 2000, the LHC will make use of advanced superconducting technology - high-field Nb-Ti superconducting magnets operated in superfluid helium and a cryogenic ultra-high vacuum system - to bring into collision intense beams of protons and ions at unprecedented values of center-of-mass energy and luminosity (14 TeV and 1034 cm-2.s-1, respectively with protons).

Performance Assessment of Industrial Prototype Cryogenic Helium Compressors for the Large Hadron Collider / Bézaguet, Alain-Arthur ; Lebrun, P ; Tavian, L

After recalling the common functional specification, as well as the main design features of the three machines, we present comparative performance results, and draw conclusions as concerns future full-scale machines for the LHC..

Supercritical Helium Cooling of the LHC Beam Screens / Hatchadourian, E ; Lebrun, P ; Tavian, L
The cold mass of the LHC superconducting magnets, operating in pressurised superfluid helium at 1.9 K, must be shielded from the dynamic heat loads induced by the circulating particle beams, by means of beam screens maintained at higher temperature. The beam screens are cooled between 5 and 20 K by forced flow of weakly supercritical helium, a solution which avoids two-phase flow in the long, narr ow cooling channels, but still presents a potential risk of thermohydraulic instabilities.

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.

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. [...]

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. [...]
