Cryogen free dilution refrigerator

NWO institute SRON wishes to purchase a cryogen free dilution refrigerator for the study and development of superconducting energy-resolving single-photon detectors (MKIDs). The system will be used in the context of a new project to develop the most sensitive MKIDs for exoplanet spectroscopy at visible to near-infrared wavelengths, and demonstrate them at a scale of ten-thousands of pixels. To that end, optical access to the cryostat from outside is required to characterise the detectors. The aim is to demonstrate...
