Paper Abstract

Advanced Split Linear and Integral Stirling cryocoolers for IR applications are controlled by external or integrated control electronics to provide a stable preset temperature at the focal plane. AIM produces a family of Split Linear Stirling coolers with integrated control electronics inside the compressor housing. The new AM 7 electronic is standardized to one configuration which meets the different input power requirements and temperature settings of all AIM coolers ranging between 10W to 105W input power. AIM has completed the development of the AM 7 electronics to improve temperature stability over the entire range of operating conditions and to optimize ramp up of input power for different cool down conditions. Thus, reduced cooldown time at high ambients and softer startup at low temperatures are achieved. Optionally, the electronics can be supplemented with an external add-on microprocessor unit for advanced system requirements. The 3rd generation electronics will be implemented into rate production 4Q2002.
