Completed TRL 6 (started at 4, targeting 6)
This project is the development of a low temperature (ambient environment) cryocooler. The development of a mechanical cryocooler capable of operating in a cryogenic environment (cryogenic mechanism).
This project is the development of a low ambient temperature cryocooler. Current Stirling cycle cryocoolers are designed to operate in an ambient environment between -40 C and 70 C (mil-spec range).
Our approach will enable a significant reduction in cooler mass and electrical power required to operate infrared sensors in the 35-40 K range, by allowing passive cooling of the cryocooler housing/heat-reject area to < 150 K.
Designing and operating a mechanical cooler at cryogenic reject temperature (200 K) brings with it several benefits, in particular, the ability to use more sensitive detectors that have optimal performance at cryogenic temperatures.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 6) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
