As the heart of cryogenic refrigerators, the helium turbo-expander affects the stable operation of cryogenic systems. The supporting component of the turbine is bearing, the mechanical properties of which are directly related to the reliability and safety of the turbine. For the helium turbo-expander, the operating speed is high and the temperature of the working wheel is low. So it is...

The superconducting linear accelerator as a booster of 15 UD pelletron accelerator is commissioned and operating for more than three years. The acceleration is achieved by a series of 97 MHZ superconducting quarter wave bulk niobium cavities at 4.2 K. In the first phase, accelerator was partly commissioned with first linac cryomodule, superbuncher, rebuncher cryostat along with 500 W ...

The nuclear fusion research is in progress for the next generation energy source in many countries. The Korean large fusion device whose name is Korea Superconducting Tokamak Advanced Research (KSTAR) is made of Nb3Sn and NbTi superconductor and it is necessary to cool down to liquid temperature. In order to proper operation of the KSTAR superconducting (SC) magnets, a Helium Refrigeration...

Superconducting magnets must be cryogenically cooled. The magnet cold mass is immersed in a pressurized bath of superfluid helium and operated at very low temperatures ( approximately 1.9 K). The distribution of helium at pressures above atmospheric pressure is a significant engineering challenge. The secret lies in the use of reliable and efficient cryogenic infrastructure like for instance...

Helium is widely used at reactor cold neutron source cryogenic system(CNS). It is well known that gas purity control is very important in an expansion-turbine-based helium refrigerator.High levels impurities such as nitrogen,hydrogen or organics can cause to process faults.What's more,high hydrogen concentration will trigger the reactor.It's owing to the hydrogen concentration monitoring in...

Helium forced flow cooling was demonstrated as a reliable way for superconducting (SC) magnets. For the large Cable-in-Conduit Conductors (CICC) in high magnetic field, supercritical helium forced flow cooling is utilized. A coiled sub-cooler for 4.5 K supercritical helium, which is the vital component of the system, has been designed and manufactured to supply required helium for the SC...
