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. [...]

Cryogenics for the Large Hadron Collider ; 2000 ed. / Lebrun, P
The Large Hadron Collider (LHC), a 26.7 km circumference superconducting accelerator equipped with high-field magnets operating in superfluid helium below 1.9 K, has now fully entered construction at CERN, the European Laboratory for Particle Physics. The heart of the LHC cryogenic system is the quasi-isothermal magnet cooling scheme, in which flowing two-phase saturated superfluid helium removes the heat load from the 36000 ton cold mass, immersed in some 400 m/sup 3/ static pressurised superfluid helium. [...]

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.

The Large Hadron Collider (LHC), a 26.7 km circumference superconducting accelerator equipped with high-field magnets operating in superfluid helium below 1.9 K, has now fully entered construction at CERN, the European Laboratory for Particle Physics. The heart of the LHC cryogenic system is the quasi-isothermal magnet cooling scheme, in which flowing two-phase saturated superfluid helium removes the heat load from the 36'000 ton cold mass, immersed in some 400 m3 static pressurised superfluid helium.

Comparison between Normal and HeII Two-phase Flows at High Vapor Velocities / Van Weelderen, R ; Perraud, S ; Rousset, B ; Thibault, P ; Wolf, P E
We present results on helium co-current two-phase flow experiments at high vapor velocity obtained with the use of the new CEA/SBT 400 W/1.8 K refrigerator [1]. For vapor velocities larger than typically 4 m/s, a mist of droplets develops from the bulk liquid interface accompanied by an increase in heat transfer at the wall. [...]
