The performance of the internal purifier has a direct impact on the liquefaction capacity of the helium liquefier. With increasing impurity level in helium, liquefaction capacity of the helium liquefier reduced significantly. In order to ensure the helium liquefier operates safely and stable, remove the impurities from the helium in the helium liquefier and improve the utilization of the...

The commissioning of China Spallation Neutron Source(CSNS) cryogenic system was completed on July, 2017. It run 258 days totally until July, 2018, and the time of the longest continuous running is 184 days. CSNS passed national accept on August, 2018. Now it is running steady from September 19th. There is no any fault in the process of running. However, cryogenic system need to be improved in...

Poster Presentation

With the development of cryogenics, the demand of cryogenic liquid increases constantly. However, there are some difficulties to control and to adjust the extraction of cryogenic liquid especially for liquid helium. Compared with the immersed pump, the ejector has huge advantages in pumping the cryogenic liquid from cryogenic dewar, like stable operation and simple structure. Considering the...
