Description

This is a pre-solicitation notice for Dilution Rerigerator an ultralow temperature quantum materials/devices measurement system (UTQMD) for the Center for Functional Nanomaterials (CFN) & the Codesign Center for Quantum Advantage (C2QA) at Brookhaven National Laboratory. The UTQMD instrument, hereafter referred to as “Instrument” shall be designed as a cryostat with an integrated high-field magnet, providing an ultralow base temperature. The system uses a helium-4 pulse tube to precool to 4K and a helium-3/helium-4 mixture to reach <10 mK temperature. The low temperature helps to minimize thermal fluctuations and thus improve the quantum coherence of the qubits/enable to observe quantum phenomena such as superconductor, exciton condensate physics. It shall support (1) electronic transport and optical spectroscopy of two-dimensional heterostructure devices and (2) RF dielectric-loss characterization using high-Q microwave resonators for superconducting qubit materials – both at temperatures < 10 mK, with expected cooling power of (typical 14 μW) on the experimental flange at 20 mK. The UTQMD should be a cryogen-free (“dry”) dilution refrigerator system and should include two separate vacuum and radiation shield set to support these two measurements. As an instrument offered to general users in a NSRC, the Instrument shall be engineered for safe, user-friendly operation (hardware and control software) and demonstrate a proven track record of low-maintenance, low-downtime operation.
