Project Description

Use of heterogeneous regenerators in sub-20K pulse tube applications Project
Pulse tube refrigerators are typically built with homogeneous regenerators. At higher temperatures (T = 35 K), heat capacity variations of the regenerator with temperature do not limit performance. At lower temperatures (T < 20K), regenerator materials are strongly peaked and limit performance over the range of the regenerator. We propose to develop regenerators that have the heat capacity of each region tailored for the temperature distribution. Pulse tube coolers at high temperature have offered increased efficiency and reliability over older cooler technology. More »
