Popis: The High Capacity Cryocooler Qualification unit (HCCQ) provides large capacity cooling at both 35 K and 85 K for space applications in which focal planes and optics require cooling. The compressor is scaled from the High Energy Cryocooler (HEC) compressor and is capable of using input powers up to 700 W. The two coaxial pulse tube cold heads are integrated with the compressor into an integral cryocooler. A thermal strap between the cold heads improves efficiency and can be positioned to provide cooling for a wide range of applied loads. The cooler will be acceptance tested at space qualification levels that include thermal performance mapping over a range of reject temperatures and power levels and launch vibration testing.
