The Department of Energy, specifically the Brookhaven National Laboratory, is seeking information regarding a Sub-Kelvin Rapid Quantum Electronics Characterization System (SKRQ) to enhance the rapid testing and prototyping of quantum devices. The system must be capable of operating at cryogen-free low temperatures, achieving 300 mK in continuous operation and 100 mK in one-shot mode, and should include essential components such as an adiabatic demagnetization refrigerator, a multi-channel sample platform for DC and RF characterization, and an automated sample loader. This procurement is critical for advancing research in quantum electronics and ensuring compliance with federal equipment procurement standards. Interested vendors can direct inquiries to Aaron Hagler at ahagler@bnl.gov for further details.
