The National Institute for Standards and Technology (NIST) seeks a replacement probe for its SQUID VSM magnetometer, critical for developing magnetic standard reference materials. The required probe must meet specific technical specifications, including a ±7 T magnetic field range, temperature control from 1.8 K to 400 K, and compatibility with existing manufacturer options. NIST intends to sole source this to Quantum Design, Inc. unless alternative sources are identified through this market research. The work will be performed at NIST’s Materials Science and Engineering Division in Gaithersburg, Maryland, though no specific budget amount is provided. Responses are requested as soon as possible, with no formal submission deadline mentioned.
