Abstract
Contact thermal conductance is much lower in a vacuum than normal pressure conditions. When we cool SR beamline optics, such as mirror components, a water cooled copper plate which is attached to the optics is used. In order to increase the effect on cooling an indium sheet or liquid metal, such as Ga, In-Ga, is inserted between the optics and the plate. We experimentally obtained contact thermal conductance in a vacuum, which was essential to computing the thermal distribution of optics. And we simulated our cooling system using a beamline mirror component.
