An introduction to cryogenics
These notes aim to give a somewhat basic introduction to the hows (and occasionally whys) of cryogenics. Cryogenics is not a very well defined term; here I have taken it to mean systems that operate at temperatures of 77 K and below, with the emphasis on systems operating below 4.2 K and above 1 K. The first two temperatures are, of course, the boiling points of nitrogen and helium respectively...

متن کاملEUROPEAN ORGANIZATION FOR NUCLEAR RESEARCH European Laboratory for Particle Physics CRYOGENICS FOR THE LARGE HADRON COLLIDER
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 remov...
متن کاملEvaluation of cryogenics-based energy storage concepts
The goal of this paper is to evaluate cryogenics-based energy storage concepts: A thermo-electric energy storage unit, which uses surplus electricity while liquefying a gas, subsequently stored at cryogenic temperature. Here we review and evaluate concepts for power generation while regasifying the liquefied gas (cryogen) using an exergetic analysis. Two cold exergy recovery cycle configuration...
متن کاملSurface-confined molecular coolers for cryogenics.
An excellent molecule-based cryogenic magnetic refrigerant, gadolinium acetate tetrahydrate, is here used to decorate selected portions of silicon substrate. By quantitative magnetic force microscopy for a variable applied magnetic field near liquid-helium temperature, the molecules are demonstrated to hold their magnetic properties intact, and therefore their cooling functionality, after their...
