Abstract
A method for cooling a superconducting device by using a sleeve assembly which thermally interconnects a two stage cryocooler with the device. In operation, the cryocooler is moveable relative to the sleeve assembly between a first configuration wherein the cryocooler is engaged with the sleeve assembly, and a second configuration wherein the cryocooler is disengaged from the sleeve assembly. The cryocooler is disposed in the sleeve assembly with the cooling element of the cryocooler positioned at a distance from the cylinder of the sleeve assembly to establish thermal communication therebetween. Also, the cooling probe of the cryocooler is in contact with the receptacle of the sleeve assembly and is urged against the receptacle to establish thermal communication therebetween. A bellows joins the cryocooler with the sleeve assembly to create an enclosed chamber therebetween and helium is pumped into the sleeve assembly to maintain an operational pressure in the sleeve assembly.
