SD System
Dilution Refrigerator Measurement System
The SD Dilution Refrigerator Measurement System is an affordable system with a fast turnaround time.
Fast Turnaround Dilution Refrigerator
To create a fast turnaround cryogenic refrigerator, we revived the form factor of our first cryogen-free dilution refrigerator measurement system. Our SD system delivers a cooldown time of < 12 hours, providing a cooling power of > 250 μW when operated at 100 mK.
The system requires no lab layout or on-site installation, and with the reduced step heat exchanger stage, the required amount of helium-3 is only 12 liters, making the system effective and affordable.

Dilution Refrigerator Measurement System
Above is a typical cooldown curve for a SD system measured with a calibrated resistance thermometer.
Pulse Pre-Cooling sequence is one of the key points in reducing the cooldown time (see spots 2 and 3). Because we do not use exchange gas, some parts of the dilution refrigerator unit stay ‘hot’ during cooldown, which prevents condensation of the helium3 –helium-4 mixture. To cool down these hot spots effectively, the mixture is repeatedly admitted from the tanks to the Still side of the dilution refrigerator to operate as an exchange gas and then pumped out again.
