Investigate design options for miniaturization of pulse-tube cold fingers. Simulate and optimize pulse-tube cold fingers for miniaturization and efficiency. Experimentally verify predicted performance by breadboard testing

For better use of cryogenic coolers, performance needs to be improved and size needs to be reduced. Miniaturization is usually achieved by increasing the drive frequency of the cooler. The miniaturization is the result of the subsequent smaller displacements in the system. However, miniaturization and higher efficiency requires optimization of efficiency. Technical and performance requirements are setup to match market needs for both COTS+ space applications and high end tactical applications.
