To provide a cryocooler interface sleeve tube, capable of engaging and disengaging thermally two stages from two constitutive portions of a superconductive device at a time.
A sleeve tube assembly for interconnecting the pulse tube two stages cryocooler thermally to the superconductive device is provided with a heat transfer cylinder, a heat transfer receptacle, and a wall face extended therebetween to define a passage. The heat transfer receptacle is formed with a tapered recess, and a tapered cooling probe of the cryocooler is pressed to contact with the heat transfer receptacle, so as to establish thermal communication therebetween. The cryocooler is engaged with the sleeve tube assembly during an operation to be thermally connected therebetween, and the cryocooler is disengaged from the sleeve tube assembly to move the cryocooler with respect to the sleeve tube assembly.
