US-FED-00000386995 - Hydrogen Maser Repair/Refurbished - Deadline August 3,2026

Combined Sources Sought Notice and Notice of Intent to Award a Sole Source Contract for Hydrogen Maser Repair/RefurbishedNotice ID: NB[ phno? redacted ]96Contract Opportunity Type: Sources Sought/Notice of IntentResponse Date: August 3, 2026Product Service Code (PSC): 6640NAICS Code: 334515BACKGROUNDThe National Institute of Standards and Technology (NIST) is conducting market research to identify alternative sources that (a) are capable of meeting NIST`s minimum requirements for the following commercial products and commercial services and (b) would be interested in competing for that requirement:The NIST Time Realization and Distribution group operates an ensemble of atomic clocks (timescale) that realizes UTC(NIST), maintenance of which is one of NIST`s mission essential functions. Some of the constituent hydrogen maser atomic clocks are reaching end of life and exhibiting degradation of performance. To maintain continued accurate operation of the timescale these aging masers need to be addressed, either through refurbishment or replacement, Additionally, there are new revisions of various modules that will improve performance and extend the lifetime of these units performing these upgrades will bring the performance of our aged units up to currently available maser atomic clocks. The services required as part of these refurbishments and upgrades are as follows:Item 1: Hydrogen maser refurbishmentQuantity: 3Specifications: 1.1: inspect hydrogen bulb, recoat if needed1.2: check and adjust RF alignment1.3: inspect thermal control board and components, repair if needed1.4: test AC/DC power module, replace if malfunctioning or too old1.5: inspect quartz oscillator, replace if not operating at spec1.6: replace ion pumps1.7: inspect physics package, replace and test if neededItem 2: Hydrogen maser upgrade to MHM–2020 levelQuantity: 3
