Abstract
A device intended for cooling an object being moved within a cryostat comprises a heat transfer section forming a contact surface for said object and means for fastening the heat transfer section to a cooling structure in such a way that said contact surface remains free. The device comprises a spring section (which is separate from said heat transfer section and which is arranged to exert on the heat transfer section a spring force pushing said contact surface in a direction in which it is intended to contact said object.
Claims15
A device for providing a thermally conductive coupling in order to cool an object being moved within a cryostat, the device comprising:
- a heat transfer section applicable for use in a vacuum at temperatures of about 4 K forming a contact surface for the object;
- fasteners coupling the heat transfer section to a cooling structure;
- a sample holder configured to move the object relative to the contact surface;
- a spring section applicable for use in a vacuum at temperatures of about 4 K which is separate from the heat transfer section and which is arranged to exert on the heat transfer section a spring force pushing the contact surface in a direction in which the contact surface is intended to contact the object;
- and
- a support ring, wherein a spring element is supported to one or more grooves at an inner surface of the support ring;
- wherein the heat transfer section comprises a plurality of heat transfer tabs arranged in a ring, wherein the contact surface comprises a surface of the heat transfer tabs facing an interior of the ring.
