Cryogenic performances of a heat exchanger prototype suitable for the superconducting HL-LHC recombination dipole D2 / Rousset, B (IRIG, Grenoble) ; Bancel, F (IRIG, Grenoble) ; Besson, N (IRIG, Grenoble) ; Bon-Mardion, M (IRIG, Grenoble) ; Claudet, S (CERN) ; Goy, T (IRIG, Grenoble) ; Millet, F (IRIG, Grenoble) ; Nivelon, P (IRIG, Grenoble) ; Perin, A (CERN)
In the framework of the future High Luminosity upgrade of the Large Hadron Collider (HL-LHC) at CERN, most superconducting magnets in the Long Straight Sections will be replaced. Among them, the new D2 recombination dipole will be a He II conduction-cooled magnet with a larger aperture than the LHC dipoles. [...]

Assessment of the operation safety margin of the HL-LHC superconducting recombination Dipole D2 in case of helium filling failure / Rousset, B (IRIG, Grenoble) ; Bancel, F (IRIG, Grenoble) ; Besson, N (IRIG, Grenoble) ; Bon-Mardion, M (IRIG, Grenoble) ; Claudet, S (CERN) ; Goy, T (IRIG, Grenoble) ; Millet, F (IRIG, Grenoble) ; Nivelon, P (IRIG, Grenoble) ; Perin, A (CERN)
After the successful completion of the cryogenic performance tests of the He II heat exchanger prototype for the D2 recombination dipole of the future HL-LHC project at CERN, specific measurements were performed to determine the operation safety margin in case of abnormal operating conditions. This is particularly relevant in case of the failure of liquid helium supply in the He II cold source. [...]

Evaluation of superfluid helium cooling schemes and application for HL-LHC recombination dipole D2 / Rousset, B (CEA INAC, Grenoble) ; Millet, F (CEA INAC, Grenoble)
Superfluid helium cooling offers the possibility to improve the performances of superconducting devices and infrared detectors with lower operating temperatures and provides extremely high heat transfer performances. In this paper, various cooling architectures are studied and the amplitude and the space distribution of the heat loads are taken into account. [...]

Semi-Dry Cooling Solutions for Future Superconducting Accelerator Structures / Chioteli, Maria (CERN) ; Koettig, Torsten (CERN) ; Onufrena, Aleksandra (CERN) ; Naydenov, Boyan (CERN) ; Adam, Thomas (CEA INAC, Grenoble) ; Bremer, Johan (CERN)
Cryogenic dry cooling solutions for Superconducting RF cavities allow for synergies with modern cavity production methods based on vacuum coating and A15 SC layer deposition methods. A proof-of-concept cryogenic performance test stand will study relevant parameters of low-temperature cooling loops with respect to the RF performance of a 1.3 GHz prototype cavity. [...]

Performance Assessment of 239 Series Sub-cooling Heat Exchangers for the Large Hadron Collider / Riddone, G ; Gilbert, N ; Roussel, P ; Moracchioli, R ; Tavian, L /FP6 Collaboration
Helium sub-cooling heat exchangers of the counter-flow type are used to minimize the vapor fraction produced in the final expansion of the 1.9 K distributed cooling loops used for cooling the superconducting magnets of the Large Hadron Collider (LHC). These components are of compact design, featuring low-pressure drop and handling very low pressure vapor at low temperature. [...]

A Cryogenic Test Station for Subcooling Helium Heat Exchangers for LHC / Roussel, P ; Jäger, B ; Tavian, L
The superconducting magnets of the Large Hadron Collider (LHC) will be cooled at 1.9 K by distributed cooling loops where counter-flow heat exchangers will be integrated. To qualify potential suppliers for the 250-units series production, prototypes of various technologies have been selected by CERN and a test station was set up at CEA-Grenoble. [...]
