Abstract
An apparatus includes: a getter material (310) disposed within a vacuum chamber (210) to absorb stray molecules within the vacuum chamber; a thermal mass (340) disposed adjacent the getter material and in thermal communication with the getter material; a cold station (312) disposed within the vacuum chamber above the thermal mass; and a convective cooling loop (310) connected between the thermal mass and the cold station and configured to convectively cool the thermal mass when the cold station is at a lower temperature than the thermal mass, and to thermally isolate the thermal mass from the cold station when the cold station is at a higher temperature than the thermal mass. The thermal mass may be water ice and may be thermally isolated from the walls of vacuum chamber by low loss support links (360, 362, 364) and/or thermal reflective shielding.
