Cooling using a cryogenic liquid and a contacting gas

A cooling apparatus includes a dewar and a quantity of liquid nitrogen within the container. Gaseous helium is contacted to the liquid nitrogen, either by contacting its top surface or by being bubbled through the liquid nitrogen. The temperature of the cryogenic liquid is lowered by the contact of...
