Abstract
A cryogenic cooling system includes a cryocooler coldhead having a cold stage. A gas circulator has a low pressure input orifice and a high pressure output orifice, and a valve has a primary port and a secondary port. The valve makes and switches fluid connections between the valve's primary and secondary ports and the gas circulator's input and output orifices. A heat exchanger has a primary portion and a secondary portion each in thermal contact with the cold stage. The primary (secondary) regenerator is positioned between the primary (secondary) port of the valve and the primary (secondary) portion of the heat exchanger. A coolant flow path has a first end in fluid communication with the heat exchanger's primary portion and a second end in fluid communication with the heat exchanger's secondary portion. The coolant flow path may be placed in thermal contact with a superconductive device.
