This is a pre-solicitation notice for an ultralow temperature quantum materials measurement system for Brookhaven National Laboratory. The instrument must be a cryogen-free dilution refrigerator reaching below 10 mK, supporting electronic transport, optical spectroscopy, and RF dielectric-loss measurements. It requires two separate vacuum and radiation shield sets for dual measurement capabilities, with a proven track record of low-maintenance, user-friendly operation. No specific budget amounts, submission timelines, or performance location beyond Brookhaven National Laboratory are mentioned. The system is intended for general user access at a National Scientific Research Center.

This is a pre-solicitation notice for an ultralow temperature quantum measurement system to be used at Brookhaven National Laboratory. The required instrument is a cryogen-free dilution refrigerator capable of reaching temperatures below 10 mK to support specific quantum materials research. It must be engineered for safe, user-friendly, and reliable operation for general users at a national research center.
