Abstract

Ball has developed a two-stage Stirling cycle cooler for high reliability space applications. Our cooler provides in excess of 400 mW of lift at 30 K at the cold stage, and up to a watt at the mid stage, for 75 W of input power. We have incorporated novel sensors that allow monitoring of the piston gap clearance to ensure that it operates without contact. We have measured thermal performance, output vibration, EMI, and the effects of launch vibration.
