This work will develop a new type of refrigerator to cool astronomical infrared detectors to less than 1K using the new pulse tube technology. USAP currently spends about $1M per year providing liquid helium to South Pole for this purpose. If this effort is fully successful than most of that money can be saved and even more science will be obtained from the South Pole telescopes. The cooler will have application at other sites as well and possibly eventually in space.

这项工作将开发一种新型的冰箱，使用新的Pulse Tube Technology将天文学红外探测器冷却至1K。 目前，USAP每年花费约100万美元，为此目的为南极提供液态氦气。 如果这项努力比大多数钱完全成功，可以节省大多数钱，甚至从南极望远镜获得更多的科学。 冷却器还将在其他站点以及最终在太空中使用应用程序。
