We describe and demonstrate the automated operation of a novel cryostat design that is capable of maintaining an unloaded base temperature of less than 300 mK continuously, without the need to recycle the gases within the final cold head, as is the case for conventional single shot sorption pumped He-3 cooling systems. This closed dry system uses only 5 l of He-3 gas, making this an economical alternative to traditional systems where a long hold time is required. During testing, a temperature of 365 mK was maintained with a constant 20 mu W load, simulating the cooling requirement of a far infrared camera. (C) 2016 Author(s).
