Abstract
The invention is directed to cooled mirror assemblies which include, in combination, a first heat exchanger plate having an upper surface forming a mirror facesheet and a plurality of cooling channels thereunder, a second distribution plate disposed underneath the first plate, which has an upper foam layer, hydraulic apparatus for feeding coolant fluid to the cooling channels and to the foam layer, and hydraulic apparatus for bleeding the coolant from the cooling channels and from the foam layer. According to one aspect of the invention the hydraulic apparatus for bleeding the coolant fluid is disposed closely adjacent the hydraulic apparatus for feeding the coolant fluid to counteract the effect of the temperature rise of the cooling fluid on the distortion of the mirror assembly.
