Abstract:
A device for cooling to temperatures lower than that of the lambda -point of helium, in which some high-pressure helium, after being cooled, expands to low-pressure and flows back to the compression device, and the remainder of the He is cooled to below its lambda -temperature forming superfluid He4 that flows through a superleak, and normal He4, and a vortex tube for communicating.
