FormFactor’s JDry cryogen-free dilution refrigerators enable easy and cost-effective cooling to temperatures below 10 mK. The JDry models have been optimized for quantum computing applications and can accommodate up to 270 semirigid cables. General-purpose configurations and astronomy/detector cooling are also provided.
The JDry cryogen-free dilution refrigerator series includes multiple standard models. All are available with easy push-button cooling using the robust and fully-automated NI LabVIEW™-based “JACoB” gas-handling system (GHS).
The JDry-500 model is fitted with a cold-plate of 508 mm (20″) diameter, and provides a cooling power of more than 450 µW at 100 mK.
