Dilution Refrigerator

The contract involves the procurement of a Dilution Refrigerator, specifically an ultralow temperature quantum materials/devices measurement system (UTQMD) for use at the Center for Functional Nanomaterials (CFN) and the Codesign Center for Quantum Advantage (C2QA) at Brookhaven National Laboratory. This sophisticated cryostat instrument integrates a high-field magnet and is designed to achieve ultralow temperatures below 10 millikelvin by utilizing a helium-4 pulse tube for precooling to 4K and a helium-3/helium-4 mixture for the final cooling stage. The system's capability to reach these temperatures is critical for minimizing thermal fluctuations, thereby enhancing quantum coherence and enabling the observation of quantum phenomena such as superconductivity and exciton condensates. It supports advanced electronic transport and optical spectroscopy of two-dimensional heterostructures, as well as RF dielectric-loss characterization with high-Q microwave resonators for superconducting qubit materials, both under stringent thermal conditions. The Dilution Refrigerator is required to be a cryogen-free ("dry") system, featuring two separate vacuum and radiation shield sets to support the distinct measurement modalities. It must provide reliable cooling power around 14 microwatts on the experimental flange at 20 mK, and be engineered for safe, user-friendly operation, incorporating both hardware and control software that ensure low maintenance and minimal downtime. The instrument will be made available for use by external researchers within a National Scientific Research Center (NSRC) framework, underscoring the importance of operational robustness and accessibility. The solicitation, identified by number BSA476517, is issued by the Department of Energy’s Brookhaven National Laboratory in Upton, New York, with a response deadline of June 1, 2026.
