Automated unit for physical research on quantum crystals at millikelvin temperatures

A cryogenic unit designed for physical research on quantum crystals at ultralow temperatures is described. The unit includes a dilution refrigerator with a hybrid 3 He circulation system, an antivibration protection system, and a system of automated control and data acquisition and processing. The construction of the basic units, the thermometry system, the algorithms for measurements, and the software for conducting research on quantum crystals by the method of precision pressure measurements are described. The unit may be used for performing a wide range of tasks in research on various condensed systems at millikelvin temperatures.
