The modern needs of the electro-optical market for small low-power and light-weight IR systems are impelling research and development of High Operating Temperature (HOT) IR detectors, requiring development of dedicated “HOT” cryocoolers. The development of cryocoolers with emphasis on the “SWAP3” configuration means small size, low weight, improved performance, low power consumption and low price, in order to optimize IDDCA for future hand held thermal sights. This paper will present the development and the progress made with the new "HOT" cryocooler, including customer data after the evaluation process, performances achieved using a common cold finger, test results update on a large series of production coolers, life and qualification test update and acoustic noise reduction. All the above mentioned information relates to the FPA temperature range of 130 - 200K for various cryocooler models based on rotary and linear design concepts. The paper will also review the progress with the latest development activities implemented in the cryocoolers and the electronic control modules in order to improve reliability and minimize regulated power consumption.
The world growth in research and development of High Operating Temperature (HOT) IR detectors impels the
development and optimization of suitable cryocoolers. The current developments at RICOR, which include three
different cryocooler models and two new controllers, are focused on the - oriented design process, meaning small
Size, low Weight, low Power consumption, improved performance and lower production cost, providing proper
cryocoolers for future hand held thermal imagers.
This paper shows the progress made during development of “HOT” cryocooler prototypes, engineering pre-production
series and qualified production series cryocoolers working at the FPA temperature range of 130 - 200K. The progress
with development of electronic control modules providing minimized regulated power consumption is also shown.
The progress in development of cryocoolers reliability is also reported in the paper.

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.
