ABSTRACT:
The invention concerns an installation for cryogenic cooling comprising: a main reservoir (1) for a two-phase cryogenic fluid wherein is immersed a superconductor device (4) to be cooled; an auxiliary reservoir (9); and a hydrostatic duct between the bases of the main and auxiliary reservoirs; the auxiliary reservoir being arranged relative to the main reservoir and being dimensioned so as to be able to receive at least a large part of the cryogenic fluid present in liquid form (2) in the main reservoir; restricting means (11) being incorporated in an output manifold (7a) connected to the main reservoir; thus, when the superconductor gets rapidly heated, cryogenic liquid from the main reservoir is delivered, by the vaporized cryogenic fluid pressure, into the auxiliary reservoir wherefrom it flows again by gravity towards the main reservoir when the pressure of the vaporized fluid decreases.
