Abstract:
A cooling system for an ultra high vacuum system configured to deposit a thin film of material on a substrate located in an active growth region, comprising:a. a vacuum chamber; b. a first cooling panel disposed within the vacuum chamber having a cryogenic fluid input port and a vapor outlet port, wherein said cryogenic panel includes a cryogenic shroud region configured to at least partially surround said substrate and a phase separator region configured to provide a near atmospheric pressure vapor barrier over the cryogenic fluid so that vapor from the cryogenic fluid may escape smoothly through said vapor outlet port; and c. a second cooling panel disposed within the vacuum chamber, configured to address and absorb heat from a source of said film material, having inlet and drainage ports opening into a reservoir and configured to circulate non-cryogenic heat absorbing fluid through said reservoir from said inlet port to said drainage port.
