The product is provided with coaxial SMA/SMP connector blocks to interface to the room-temperature electronics and the chipholder at the mK stage. Vacuum feedthroughs are designed to carry multiple flexes and are compatible with most fridge types. The chain of integrated attenuators and low pass filters is configured for flux bias currents, shielding the bias loop from undesired high frequency noise while allowing short risetimes. Below the 100 mK plate, integrated infrared filtering is positioned and thermalized with a slope of -1.5 dB/GHz to further filter out high frequency radiation.
The passive heatload is 600 pW per channel at 10 mK due to the superconducting material used.
System Integration
There is a wide variety of cooling solutions for quantum computing and low temperature experiments, ranging from lab size dilution refrigerators to small 4K table-top systems. As an i/o provider, it is our task to connect quantum devices and cold experiments to the control electronics regardless of the cooling implementation. To that end we have developed standardized solutions that fit (or can be made to fit) all fridges.
Whether you are purchasing a new system or want to refurbish your current system, Cri/oFlex® provides a solution.
Wiring Ports
Have a spare port in your fridge and want to add extra lines or replace an existing wiring port with a higher density cabling solution?
We supply vacuum feedthroughs, Thermal clamps, Brackets and Cri/oFlex® laminates for all standard ports you will find in dilution refridgerators.
