The European Spallation Source (ESS) is a neutron-scattering facility being built with extensive international collaboration in Lund, Sweden. Three cryogenic plants with a vast cryogenic distribution system meet the cooling requirements of the superconducting RF cavities in the accelerator (ACCP), the cold hydrogen moderators in the target (TMCP), a cryomodule test stand and the sample...
Another neutral beam injector (NBI-2) was added for the KSTAR plasma experiments, recently. It requires a deuterium gas cryo-condensation system with the pumping speeds over one million liter/sec. For this purpose, many cryo-panels and a liquid helium cryogenic system were designed and constructed take into accounting the previous NBI. After the independent performance tests of the NBI-2, it...
The “CFETR integration engineering design” project and the program to develop an “integrated research facility for key systems of fusion reactor” have been granted by China in 2017. For the CFETR cryogenic system, an engineering conceptual design will be accomplished in 2020. The cryogenic system heat load is being calculated basing on the updated parameters of CFETR: a major and minor radius...
China Initiative Accelerator Driven System (CiADS) is a high-power nuclear waste processing research facility being built at huizhou, Guangdong, CHINA. CiADS consists of a 2.5 MW superconducting proton linac with energy of 500 MeV and 5 mA, a liquid lead bismuth eutectic (LBE) cooled fast reactor with 10 MW, and a granular flow target employed to coupling the accelerator and the sub-critical...
Large scientific facilities applying HeII technologies usually use the Joule-Thomson expansion for the final production of saturated superfluid helium at their cryomodules or magnet cryostats. Required cooling power is usually delivered by the flow of subcooled liquid helium flow at
4.5 K and 3 to 4 bar(a). Then, the 4.5 K helium is precooled in a heat exchanger and throttled to a...
