Summary
The fridge was optimized to work without external pumps, with the main cryostat providing a 4.2 K thermostat at sea level and a 4.0 K one at high mountain pressure conditions. The measured ultimate temperature of the fridge is 290 mK, with a hold time of 81 h. The external heat input on the cold flange is about 35 microW, with the main bath at 4.0 K. The recycle time is 8 h with a heat input on the thermostat during recycling of about 6800 J.
