摘要： Cooling apparatus is provided which comprises a mechanical refrigerator and a heat pipe. The mechanical refrigerator has 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. The heat pipe has a first part coupled thermally to the first stage of the mechanical refrigerator and a second part coupled thermally to a cooled member which may comprise the second stage of the mechanical refrigerator. The heat pipe is adapted to contain a condensable gaseous coolant when in use. An example coolant is Krypton. The apparatus is 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. When the cooled member is the second stage of the mechanical refrigerator, the heat pipe provides heat between the higher and lower temperature cooled stages during cooling. An associated method of operating such apparatus is also described.

摘要： A method is provided of operating a cryogenic cooling system, in which a target region for receiving a sample is cooled by a dilution refrigerator containing an operational fluid. Firstly any operational fluid is removed from the dilution refrigerator. Target apparatus comprising the sample is loaded from a high temperature location to the target region. The target apparatus is then pre-cooled in the target region to a first temperature using a mechanical refrigerator. The operational fluid is then supplied to the dilution refrigerator and the dilution refrigerator operated so as to cool the target apparatus in the target location to a second temperature that is lower than the first temperature.A suitable system for performing the method is also disclosed.

摘要： An ultra-low temperature, ULT, rotator apparatus for effecting and monitoring an orientation of a rotatable member within a magnetic field is provided. The apparatus comprises: a rotator mechanism adapted to control rotation of the rotatable member, and a sensor arrangement mounted to the rotatable member and configured to output a signal representative of the orientation of the rotatable member with respect to a direction of the magnetic field. The sensor arrangement comprises one or more ULT magnetic sensors. Each of the one or more ULT magnetic sensors is adapted, when in use at ultra-low temperatures, to monitor magnetic field strength with a field responsivity of at least 1 x 10-4 VT-1 while generating heat at a rate of less than 1 x 10-8 W.

摘要： A method for forming a gas gap heat switch is provided comprising the following steps: (a) providing first and second conductors, and first and second connecting members, wherein the connecting members each have a thermal conductivity at least five times smaller than that of the conductors when at a temperature of 100K; (b) fusing the first conductor to the first connecting member and the second conductor to the second connecting member; (c) aligning the conductors such that the first and second conductors extend along a common major axis; (d) bringing proximal ends of the aligned conductors into contact with each other when said conductors are at a first temperature; and (e) joining the first connecting member to the second connecting member so as to form a chamber around at least the proximal ends of the conductors. The connecting members forming the chamber each have a coefficient of thermal expansion that is less than that of the conductors such that, when the conductors are cooled to a second temperature which is below the first temperature, the length of the conductors along the major axis decreases with respect to the length of the chamber along the major axis so as to form a gap between the proximal ends of the conductors. The switch is also arranged to selectively provide a thermally conductive gas into the chamber when in use to cause operation of the switch.
