 ABSTRACT 

 The world growth in research and development of High Operating Temperature IR detectors impels the development process and the optimization of HOT Cryocoolers at RICOR. The development emphasizes the “SWaP” configuration which is Small Size, Low Weight and Low Power consumption, in order to optimize IDDCA for future hand held thermal sights and other various applications. 

This paper will present optimization tests results performed on HOT Lab Demonstration Cryocoolers at the temperature range of 130 – 180K FPA and also will review the development activities that will be implemented in order to minimize “Idle electronic and mechanical losses”, hence minimizing the regulated power consumption. The new Cryocoolers developed for HOT detectors aim for higher reliability which is analyzed and reported in the paper.
