The Argonne Tandem Linac-Accelerating System (ATLAS) superconducting heavy-ion linac is cooled by forced flow of liquid helium supplied by a 300- and a 180-W refrigerator. Outgoing flow is recondensed between heat loads by heat exchange with return flow. Control valves limit line pressure by diverting flow to return stream heat exchangers. Heater controls can maintain constant pressure or level in two helium Dewars, or constant flow for increasing or decreasing liquid level. A power meter reads excess refrigeration capacity. A stable, constant pressure liquid-nitrogen system utilizes flash loss cold gas in the refrigerators, and supplies stable low-pressure nitrogen for general cooling and shielding.
