There are two 450W and one 890W helium cryogenic systems, which were installed at Taiwan light source (TLS) and Taiwan photon source (TPS), respectively. The TLS helium cryogenic system were used for one SRF cavity and five superconducting magnets. The TPS helium cryogenic system was used for two SRF cavities at the present stage. These three helium cryogenic system experienced the pressure...
As hydrogen continues to gain momentum as a clean fuel and energy carrier in industrial sectors, hydrogen liquefaction has emerged as an essential part of the supply chain to reduce transportation and storage costs. Hydrogen has historically been produced from electrolysis and steam-methane-reforming, but as the market continues to grow, biproduct hydrogen from chemical processing and biomass...
In this paper, reliability analysis of a large-scale helium cryogenic refrigeration system with cooling capacity of 2500W@4.5K/500W@2K is studied. Reliability model and failure rate of the refrigeration system based on fault tree is developed. It consists of liquid helium and superfluid helium subsystems. The key components include two helium screw compressors, six gas bearing expansion...
At the European Spallation source (ESS), 2 GeV proton beams with a power of 5 MW are injected on a rotating tungsten target wheel with a repetition of 14 Hz and a pulse length of 2.86 ms to produce high energy spallation neutrons. The high-energy neutrons are slowed down to cold and thermal energies by the moderators, which consists of a thermal water pre-moderator and two liquid hydrogen cold...
Cryogenic compressed hydrogen is one of the most possible hydrogen storage methods to achieve a high storage density, which can meet the long-distance driving demand of hydrogen fuel cell vehicles. In the process of transportation, the precooling process of cryogenic compressed hydrogen is very important. This precooling process requires a continuous refrigeration power from ambient...
