Abstract

In recent years, the trend of moving IR detectors to operate from standard 77K to the High Operating Temperature (HOT) of 150K, drives RICOR’s onward development focusing on SWaP-C, a new family of miniature cryocoolers, alongside continuing to make improvements to existing cryocooler models. The main objective for the development of a new family of cryocoolers is to focus on SWap-C by creating cryocoolers that maintain a small size, low weight, low power consumption and an attractive cost. This effort has yielded advanced Linear & Rotary miniature Cryocoolers named K580, K588 and K590. This paper will review the progress made with qualification and the move to production of the K590 Linear Dual Opposed model using customized cold finger & engineering efforts to optimize the K588 model that based on the same compact dual opposed compressor integrated with a common cold finger. In addition, the paper will present the improvements made for K580I Integral Rotary Model with lower induced force level and will review the accumulated experience of 3 mature models under production named K527, K562S and K562SI.
