Aalto University School of Science, Department of Applied Physics is conducting research on superconducting quantum circuits at milli Kelvin temperatures and low noise levels. We seek a complete turnkey, standalone dilution refrigerator pre-cooled with a pulse tube refrigerator. It must be suitable for low-noise and high resolution measurements at microwave frequencies and have the ability to apply DC control signals. It must be fully equipped with temperature sensors, radiation shields, and attenuated coaxial cables.
