【 摘 要 】

This paper introduces a Software Development Kit (SDK) that enables the creation of custom software applications that automate the control of a cryo-refrigerator (Quantum Design model GA-1) in third party instruments. A remote interface allows real time tracking and logging of critical system diagnostics such as pressures, temperatures, valve states and run modes. The helium compressor scroll capsule speed and Gifford-McMahon (G-M) cold head speed can be manually adjusted over a serial communication line via a CAN interface. This configuration optimizes cooling power, while reducing wear on moving components thus extending service life. Additionally, a proportional speed control mode allows for automated throttling of speeds based on temperature or pressure feedback from a 3rdparty device. Warm up and cool down modes allow 1stand 2ndstage temperatures to be adjusted without the use of external heaters.
