The automated cryogenic system designed to investigate quantum crystals at millikelvin temperatures

摘要

A cryogenic complex designed to investigate quantum crystals at ultralow temperatures is de- sribed. The complex includes a dilution refrigerator with hybrid ~3He circulation, an antivibration protec- tion, a control system and a data acquisition and processing one. The main components, the thermo- metry system, the measuring algorithm and the soft- ware used to investigate quantum crystals by preci- sion pressure measurements are described. The complex system may be used to solve a wide circle of problems concerning the study of different con- densed systems at millikelvin temperatures.
