Development and demonstration of cryogenic coolers for space applications discusses wire
mesh sintering
The objectives of this paper are to develop
and demonstrate advanced cryogenic coolers for future space applications. These
coolers are required to have a high efficiency, low cost, an extended life, and
good temperature stability. The technologies being developed were chosen to
increase the usefulness of detectors and of overall sensor systems. Emphasis was
placed on technologies that extend mission lifetimes (efficient, durable
coolers) and those that extend the available range of operating temperatures
(coolers for < 10 Kelvin). These activities blend analysis with component
development and include extensive in-house characterization, development, and
technology demonstration. In carrying out the program, the work is coordinated
with users and maximal use is made of existing facilities and expertise in
industry, universities, and government agencies. The use of sintered copper mesh
materials is discussed in shallow coolers is discussed.
