The National Institute of Standards and Technology (NIST) is conducting market research through a Sources Sought Notice to identify potential sources for an ultra-high vacuum (UHV) sample bakeout chamber. This chamber is essential for assessing material outgassing during heating, as NIST's Sources and Detectors Group requires equipment that can operate under UHV conditions for precision radiometry across the electromagnetic spectrum. Interested vendors must provide detailed information about their capabilities, including technical specifications, customization options, and service offerings, with responses due as soon as possible to the primary contact, Jenna Bortner, at jenna.bortner@nist.gov. This notice is for market research purposes only and does not constitute a commitment to issue a solicitation or award a contract.
