Abstract With the increasing demand for high temperature cryoelectronics and sensitive spaceborne infrared imaging and detection systems, reliable mechanical cryocoolers have become an enabling technology. These cryocoolers share two undesirable characteristics, vibration and heat generation. Vibration causes deflections in attached structures, adversely affecting sensor systems alignment and inducing spurious electrical signals. Heat generation increases cryocooler temperature, thereby reducing efficiency, reliability, and lifetime. Technology Applications, Inc. (TAI), with the support of CSA Engineering, Inc., developed a multi-axis Thermally Conductive Vibration Isolation System (TCVIS) for cryocoolers under a SBIR Phase II program for the Space Vehicles Directorate of AFRL (Contract No. F29601-97-C-0114). The vibration isolation goals were a multi-axis 50∶1 vibration reduction at the cryocooler drive frequency, and a 10∶1 reduction at two or more harmonics.
