Cryogenic Wiring and Heat Sinking Integration

The contract calls for the design and installation of cryogenic internal wiring with integrated heat sinking to achieve a minimum cooling power of 250 microwatts at a temperature of 100 millikelvin. This work must ensure thermal stability and electrical performance under extreme low-temperature conditions, requiring specialized materials and engineering solutions to minimize parasitic heat loads while maintaining signal integrity. The project demands precise fabrication and assembly techniques tailored for ultra-low-temperature environments, with all components and methods subject to rigorous validation to meet the specified thermal performance threshold. This subcontract is issued by the National Institute of Standards and Technology under the U.S. Department of Commerce and is targeted for performance in Boulder, Colorado, with a response deadline of July 17, 2026. The North American Industry Classification System code 335999 indicates the work falls under other electrical equipment and component manufacturing, suggesting the need for advanced manufacturing capabilities beyond standard electronics assembly. The solicitation is open to qualified contractors capable of delivering cryogenic systems with proven expertise in low-temperature thermodynamics, materials science, and precision wiring integration, with no set-aside preferences indicated.
