RICOR Ltd. En Harod (IHUD) 18960, Israel AB STRACT Two-dimensional infrared focal plane array detectors in general are characterized by a significantly larger size and thermal mass than the traditional discrete element detectors. Usually, they contain an "on-board" signal processor. The size and thermal mass impact is significant in the radiation shield/cold optics subassembly In order to achieve miniaturization, low input power and fast cool down time, a combined team of Cincinnati Electronics Corporation, Mason, Ohio, and RICOR-Cryogenic and Vacuum Systems, EnHarod (IHUD), Israel are working on the development of a Miniature Integral Cooler/Dewar Assembly-1DCA specially tailored for 2-D FPA type detectors.A progress report, based on accumulated experimental data gathered through the operation of engineering models of this type in a laboratory level and in a system level under various conditions will be presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
