Patent ID: 7812606

Claim:
A nuclear magnetic resonance (NMR) apparatus comprising: a cryogenically-cooled, thermally-conductive NMR probe support situated within an NMR probe; a NMR probe circuit component of the NMR probe; and a demountable thermal contact assembly for establishing a demountable thermal connection between the NMR probe circuit component and the NMR probe support, the thermal contact assembly comprising a contact assembly body connected to a first structure selected from the NMR probe support and the NMR probe circuit component, a collet positioned within the contact assembly body, the collet having a front slotted collar and a back collet threaded surface, a pin extending through the front collar of the collet and connected to a second structure selected from the NMR probe support and the NMR probe circuit component, and a threaded collet fastener having a fastener threaded surface engaging the collet threaded surface to secure the collet to the contact assembly body and thereby establish the demountable thermal connection between the NMR probe circuit component and the NMR probe support through the pin, collet, and contact assembly body.
