CryogenF
The system employs a power-savvy and quiet pulse tube cryocooler with remote distribution valve. It takes only 40 hours to cool to the base temperature of 15 mK thanks to a common vacuum space and efficient mechanical heat-switch design.
The current system has a measured cooling power of 120 microwatts at 100 mK with a single mechanical vane pump, and can be upgraded to an automated gas handling system, Janis model GHS2, equipped with a more powerful oil-free hermetic 6-stage Roots pump. This upgrade insures full remote control of the cooling process, as well as higher cooling power.
