Paper Abstract

Recent developments of small SWAP2 (Size, Weight, Power, and Price) cryocoolers designed for HOT IR electro-optical devices have already yielded a range of commercial products available from the leading companies in this area. To date, RICOR has contributed to this range the two cryocoolers – K580 rotary model, and K588 linear model. However, continuous demand of the market in further improvements did initiate further K588 model development, intended to meet even more challenging requirements of SWAP2 than its predecessors. The improvements implemented in this new development do involve the whole range of the SWAP2 parameters, still providing withstanding at challenging environmental conditions of shock, vibration and ambient temperature. This paper provides a report on the status of new K588 linear HOT cryocooler development, including specification, outline, prototype performance and pre-qualification test results under specified shock, vibration and ambient temperature. The current phase of the project resulted in meeting of the most specified parameters, while some of them still need further improvement at the next project phase.
