Paper Abstract

The development of a ceramic applique for the vibration suppression of a cryocooler coldfinger is a part of technology demonstration flight experiment. Three sectors of a piezoelectric PZT bonded to the coldfinger are used as actuators to control the motion of the tip. A technique for bonding the PZT material to the coldfinger was developed that minimizes tensile stresses in the ceramic during operation. Extensive development testing has been performed to verify the efficiency of the adhesive and the coldfinger performance at cryogenic temperatures. The problems encountered during the fabrication and assembly of the coldfinger are described. Results of tests are summarized.
