Description
The Brookhaven Science Associates, LLC is seeking a quotation for a dilution refrigerator, an ultralow temperature quantum materials/devices measurement system. The system should be designed as a cryostat with an integrated high-field magnet, providing an ultralow base temperature. The offeror must have previous experience designing, manufacturing, installing, and commissioning cryogen-free dilution refrigerator systems of comparable complexity. The offeror must also have a robust instrument service engineer network in the United States and a robust Quality Assurance program for the design, manufacture, and testing of all systems and equipment provided.
Some key features of the system include:
* A helium-4 pulse tube to precool to 4K and a helium-3/helium-4 mixture to reach <10 mK temperature
* Two separate vacuum and radiation shield set to support electronic transport and optical spectroscopy of two-dimensional heterostructure devices and RF dielectric-loss characterization using high-Q microwave resonators for superconducting qubit materials
* A cryogen-free ("dry") dilution refrigerator system
* A proven track record of low-maintenance, low-downtime operation
* OSHA NRTL certified instruments
