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冰箱，利用新的脉冲管技术将天文红外探测器冷却到1K以下。USAP目前每年花费约100万美元为南极提供液氦。如果这一努力完全成功，那么大部分资金就可以节省下来，甚至从南极望远镜中获得更多的科学知识。这种冷却器也将应用于其他地点，最终可能应用于太空。
