Abstract:"We propose to develop a multi-stage hybrid cooler capable of providing 1 W of cooling at 10 K. To achieve the most efficient and reliable hybrid cooler possible, we propose to combine a multi-stage, linear-drive pulse tube with a low-temperaturereverse-Brayton stage. In this way we will take… more
Abstract:NASA requires cooling of detectors for space telescopes. Detector temperatures as low as 0.05 K are being specified for a number of missions. A number of physics experiments proposed on the International Space Station require very low temperatures as well. Thus, NASA has identified a dilution… more
Abstract:For the spaceport of cryogenic fluids (e.g., liquid hydrogen) NASA requires cryocoolers that can provide more than 10W of cooling at 20K. We propose to develop a two-stage 20K pulse tube cooler (PTC) to fulfill this need. PTCs embody the high efficiency, high reliability, and low vibration required… more

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
