Vacuum break in particle accelerators is a major concern due to risks associated with personnel and extensive equipment damage. Continuing research in our lab focuses on the sudden loss of vacuum in the liquid helium cooled beam-line tubes of superconducting particle accelerators. In our previous research, we studied nitrogen gas propagation in a uniform tube system immersed in both normal...

The comprehensive research facility for key systems of fusion reactors was included in the “13th Five-Year Plan” priority project in China. In order to meet the requirements of cryogenic testing of the large superconducting magnets, it is proposed to build a 3kW@4.5K refrigerator and carry out research on 3kW@4.5K helium cryogenic system. To evaluate the reliability of the 3kW refrigerator,...

In mechanical experiments, the stirling cooler is often rigidly contacted with the fixture, and mechanical condition applied on the cooler is the same as that generated by the shaking table. In some special cases, flexible design is needed between the cooler and the fixture, and the relative position between them will change during the vibration process. Then, the mechanical condition on the...

Liquid natural gas (LNG) boiling process concerns majority of LNG applications because of a need of its regasification. Depending on pressure an equilibrium temperature of LNG is 112-160K. The low boiling temperature of LNG makes the vaporisation process complicated. An important risk of the regasification is related to a possibility of a solid phase formation (freezing of a heating fluid)....

Cryogenic fluids are used for wide range of industrial and laboratory applications. Vacuum or supper-insulated transfer lines are efficiently used to transfer these fluids from the storage Dewars to the end applications. As the heat transfer to the cryogens flowing through the transfer line cannot be completely eliminated, many a times two-phase flow occurs during the transfer process. It is...

It can measure temperatures down to 50 mK using a lock-in amplifier and drive heaters from microwatts to watt.
This flexible solution is based on a 19 inch rack featuring a processor card and five slots.
Currently these slots can accept three types of cards following:
