This paper presents the development of a two-stage pulse tube cooler for space applications. The staged cooler incorporates an integral High Efficiency Cryocooler (HEC) pulse tube cooler with a linear cold head and a split second remote coaxial cold head. The two-stage cold head was designed to provide simultaneous large cooling power at 95 K at the linear cold head and 180 K at the split coaxial cold head. The innovative staging design allows up to 50 cm of separation between the cold heads. The cooler is compatible with the existing HEC flight electronics.
