Specialized Test Equipment Fabrication and Integration

NASA Goddard Space Flight Center is seeking a small business contractor to design, fabricate, and integrate specialized test equipment for use in cryogenic-free dilution refrigerator systems. The work involves creating custom test fixtures, sample holders, and instrumentation interfaces that must operate reliably under extreme low-temperature conditions without traditional cryogens, requiring advanced materials selection, thermal management, and electromagnetic compatibility considerations. The equipment must be engineered to interface seamlessly with quantum sensing and measurement systems, ensuring precision, stability, and long-term operational integrity in a highly sensitive laboratory environment. The contract is a total small business set-aside under NAICS code 332721 and is structured as a subcontract. Proposals must be submitted by May 15, 2026, at 4:00 PM ET, with performance based at Greenbelt, Maryland, 20770. The project demands expertise in precision mechanical design, cryogenic-compatible fabrication techniques, and integration of electronic and mechanical systems for ultra-low temperature applications. All work must comply with NASAs operational standards and quality requirements, with delivery of fully tested and documented hardware ready for immediate deployment in mission-critical research environments.
