Abstract: A cryogenic cooling system comprises a vacuum chamber, a first support system for cold plates in said vacuum chamber, and a second support system for heat radiation shields in said vacuum chamber. Coupled to said first support system and supported thereby are a plurality of mutually parallel cold plates displaced from each other in a first direction. Said first direction is defined as the direction perpendicular to said cold plates. Coupled to said second support system and supported thereby are a plurality of at least partially nested heat radiation shields. Each of said heat radiation shields is configured to shield a respective sub-space adjacent to a corresponding one of said cold plates. At least a first cold plate of said cold plates is a modular cold plate comprising two or more sections adjacent to each other on the same level in said first direction, said sections being coupled to said first support system independently of each other.

Abstract: A device intended for cooling an object (601) being moved within a cryostat comprises a heat transfer section (602) forming a contact surface for said object (601) and means for fastening the heat transfer section (602) to a cooling structure (604) in such a way that said contact surface remains free. The device comprises a spring section (605) which is separate from said heat transfer section (602) and which is arranged to exert on the heat transfer section (602) a spring force (606) pushing said contact surface in that direction in which it is intended to contact said object (601).

Abstract: Heat exchanger material for use in heat exchangers of cryogenic cooling systems comprises solid material rendered into its final form in an additive manufacturing process. The material has a surface-to-volume ratio of at least 10 5 1/m. The invention also relates to a cryogenic cooling system and a heat exchanger for transferring thermal energy to or from a liquid cryogen. The aim of the invention is to overcome the difficulties in making thermal energy transfer between a liquid cryogen and an adjacent solid structure.
