High resolution space IR detection requires the use of cooled detectors. The broadness of the landscape of cooling systems that are available nowadays allows to choose the suited cryocooler for each of the applications.
Yesterday, rotary Stirling coolers were usually not the preferred choice in space application context because of their lower level of reliability and availability compared to...
Over the past eight years, BAE Systems Inc. has been working with teammates that include Sunpower/Ametek, Iris, and SDL on next generation cryocooler systems. These cryocooler systems have been sponsored by both internal and external customers and has resulted in development of a product line of low cost, low EFT, high capacity, high reliability cryocooler systems. A key element is the high...
Reliability is a major driver in design decisions for the products of Thales Cryogenics. In the past years Thales Cryogenics has put their attention to the High-Availability 24/7 application of cryocoolers in combination with detectors. Several technical decisions have been aimed at the improvement in increased availability.
This paper highlights an updated approach of Thales Cryogenics to...
Thermal margins are critical to the development, the production, the test, and ultimately the performance of thermal subsystems. And, the subset of thermal subsystems that are cryogenic are even more reliant on thermal margins for success. Thermal uncertainty margins cover the inherent uncertainty, due to both design and analysis limitations, of predicting performance in space. They are not...
Linear cryocoolers are being used for space sensor cooling for multiple proliferated and strategic space missions. The cooling, lifetime and cost requirements are unique to each mission. Multiple commercial or build-to-print versions of the mechanical cryocooler exist, but the development of mating and optimized cryocooler control electronics has lagged behind the mechanical cryocooler. To...
Over the past four years BAE Systems Inc. has been developing the Modular Advanced Cryocooler Control Electronics (MACCE). This new cryocooler control electronics architecture leverages modularity and scalability in performance supporting a wide range of cryocoolers including 4K Hybrid Systems (J-T + Pre-Cooler), Pulse Tube Cryocoolers, and Stirling Cryocoolers. The MACCE design includes the...
As enhanced cryocooling capabilities for space imaging technology continue to advance, Iris Technology is committed to pioneering the development of high performance Cryocooler Control Electronics (CCE) to deliver significantly increased power output and facilitate the concurrent operation of multiple cryocoolers within a discrete system.
Iris Technology's upcoming high power CCE is a leap...
Thermoacoustically driven cryocoolers have been an area of significant interest due to the driving mechanism being heat, which hence eliminates the need for moving mechanical parts and thus increases simplicity and reliability. A small-scale travelling-wave thermoacoustic Stirling cryocooler of this nature was designed and optimised in the thermoacoustic modelling software ‘DeltaEC.’ The...
