Replacement High-Performance Cesium Beam Tube for 5071A Frequency Standard

The Department of Commerce’s National Institute of Standards & Technology (NIST) is conducting market research to identify potential vendors capable of manufacturing a replacement high-performance cesium beam tube for the 5071A frequency standard. This sources sought notice, classified under NAICS code 334519, aims to gather information from both small and large businesses within the United States before determining the acquisition method. While no solicitation or contract award is currently planned, the market research results will guide NIST on whether a small business set-aside is appropriate, depending on the presence of at least two qualified small business suppliers. Interested companies are invited to submit capability statements of no more than four pages by May 14, 2026, highlighting their company name, manufacturing details, product origin, relevant product specifications, lead times, and any additional pertinent information. The focus is on vendors experienced in producing cesium beam atomic clocks or similar precision measuring devices. This is a preliminary step with no commitment from the government to award a contract or pay for any submitted information. Responses must be submitted electronically to the designated contract specialist at NIST, with an emphasis on transparency about the manufacturing country, and brochures or marketing materials will not be accepted.
