CEC-01 - Large-Scale Refrigeration and Liquefaction
Poster Presentation
In the course of the studies for the next generation particle accelerators, in this case the FCC-hh, different aspects are being investigated. One of these is the heat load on the beam tube, which results mainly from the synchrotron radiation. In case of the FCC-hh, a heat load of 500 kW is expected. The heat has to be absorbed at 40 to 60 K due to vacuum restrictions. In this range,...

Poster Presentation
Following recommendations of the recent update of the European strategy in particle physics, CERN has undertaken an international study of possible future circular colliders beyond the LHC. This study considers an option for a very high energy (100 TeV) hadron-hadron collider located in a quasi-circular underground tunnel having a circumference of 80 to 100 km. The synchrotron radiation...

CEC-01 - Large-Scale Refrigeration and Liquefaction
Poster Presentation
A new and systematic naming method is proposed as academic nomenclature of cryogenic refrigeration cycles for liquefaction of natural gas. Over decades, a large number of LNG processes have been designed and patented, even though only a few are operational in practice, including SMR (single mixed-refrigerant), C3-MR (propane-precooled mixed-refrigerant), cascade, or AP-X processes. These...

For the fabrication of a cryopump with large pumping speeds for use in tokamaks, in particular, for gases such as helium and hydrogen, different activated carbon sorbents (with surface areas ~ 2000 m2/g) in the form of granules, spheres and cloths have been developed. These sorbents are adhesively bonded on a small size hydroformed (in-house developed technology) cryopanel of size ~500mm x 100...

Thermal shield (TS) will be installed in the ITER Tokamak to protect the superconducting magnet from thermal radiation from cryostat and vacuum vessel. The TS is cooled by 80 K helium supplied from cryoplant. The emissivity of TS surface must be maintained below 0.05 by bath-type silver electroplating. The TS is to be fully procured by Korea and it will be assembled in the ITER Tokamak by ITER...

Poster Presentation
The High Energy and Intensity HIE-ISOLDE is a facility under construction at CERN whose target is ultimately to produce radioactive ion beams at 10MeV/u maximum energy in order to significantly expand the nuclear physics programme carried out by REX-ISOLDE. In its final stage the new upgrade will be composed of two low-β and four high-β superconducting cryomodules. The first high-β cryomodule,...
