1. 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 forming a contact surface for said object,
means for fastening the heat transfer section to a cooling structure in such a way that said contact surface remains free,
wherein 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 the contact surface is intended to contact said object;
wherein said heat transfer section comprises:
a fastening ring having an inner edge, and
a plurality of heat transfer tabs which are fastened at one end to the inner edge of the fastening ring and another, free end of which is directed in a substantially perpendicular direction to a plane defined by the fastening ring; and
wherein said spring section comprises:
a support ring fastened on top of said fastening ring and having an inner surface, and
a plurality of spring tabs supported to the inner surface of said support ring and arranged to exert on said plurality of heat transfer tabs said spring force.
