Abstract
Superfluid helium will be used to produce ultracold neutrons at the research nuclear reactor. Way of direct pumping helium vapor is proposed to remove heat from the superfluid helium. Cryogenic cycle with superfluid helium was developed. Maximum heat and flow rate cycle parameters were calculated taking into account performance of cryogenic and vacuum facilities. Maximum of 45,8 W can be removed from the liquid helium at a temperature level of 1,3K.
Keywords: cryogenic cycle, superfluid helium, vacuum pumping.
