Abstract
Thermal link device for use between an end surface of a cold finger of a cryogenic machine, at cryogenic temperature when in use, and a load, comprising: PA1 a plate confronting said end surface, for connection with the load, mechanically separate from the end surface and defining a condensation and vaporization gap with said end surface, PA1 a capillary pumping element in said gap, PA1 a flexible wall defining an enclosure accommodating said gap and surrounding at least said end surface and a portion of a cold finger which is close to said end surface, and PA1 gas means in said enclosure, said gas means including at least one gas having a condensation temperature selected responsive to a cryogenic temperature to be given to the load.
