Automated control and data acquisition for a small dilution refrigerator

摘要

An automatic temperature controller and data acquisition system for use with a dilution refrigerator is described. The unit is controlled by a 16hyphen;bit home microcomputer and operates and reads a resistance bridge, capacitance bridge, and temperature controller. Interfacing is achieved with common components and minimum additional wiring. Flexibility is retained in the software to allow application to several types of measurements.
