Claim Text:
1. Cooling apparatus comprising:— a mechanical refrigerator having a first cooled stage and a second cooled stage, the second cooled stage being adapted to be coupled thermally with target apparatus to be cooled; and, a heat pipe having a first part coupled thermally to the first stage of the mechanical refrigerator and a second part coupled thermally to a cooled member, the heat pipe being adapted to contain a condensable gaseous coolant when in use; the apparatus being adapted in use to be operated in a first cooling mode in which the temperature of the cooled member causes the coolant within the second part of the heat pipe to be gaseous and the temperature of the first stage causes the coolant in the first part to condense, whereby the cooled member is cooled by the movement of the condensed liquid from the first part to the second part of the heat pipe; wherein the heat pipe further comprises walls within which are positioned flexible bellows configured to dampen vibrations between the first cooled stage and the target apparatus.
