Request for Information: Modular and Sustainable mK Cryogenic Equipment DARPA-SN-26-40
Summary
AI-generated · Jan 28, 2026Feasibility and application space for modular, interconnected cryocoolers with sub-kelvin stages that require no helium-3. DARPA’s Microsystems Technology Office seeks information on disruptive concepts significantly beyond the current state of the art, backed by preliminary experiments, predictive modeling, or analytical work.
Focus on solutions that completely eliminate helium-3 in sub-kelvin cooling and deliver non-incremental innovations over today’s architectures; approaches that merely reduce helium-3 use or offer incremental improvements will not be of interest.
The Defense Advanced Research Projects Agency (DARPA) Microsystems Technology Office (MTO) seeks information on the feasibility and application space of modular, interconnected cryocoolers featuring sub-kelvin stages requiring no helium-3. DARPA is interested in disruptive technology concepts significantly beyond the current state of the art, backed by preliminary experiments, predictive modeling, or analytical work. Approaches not of interest include solutions for reducing, but not eliminating, helium-3 in the sub-kelvin stage(s) and solutions providing incremental advancements on today s architectures.
