Abstract

The world is becoming more enthusiastic about exploring the space. Researchers all over the world are developing new technologies every single day that can help us to look far beyond our galaxy. We require devices which can help us to look faraway objects in deep space precisely. We require detectors which can detect even a weak signal that is coming out from any celestial body from a faraway distance. For that, detectors must be highly sensitive and that is only possible when an instrument operates at a very low temperature, below 50 K. Space based companies are involved in research, development and demonstrations of applications of space technology in the field of remote sensing and satellite navigation. This includes research and development activities that require high sensitive detectors which need cryocooler at its heart for the best outcome from the detectors. Stirling cryocoolers are now used for cooling infrared detectors for many space applications. This paper deals with design of Stirling cryocooler for space application of 1 W at 80 K. It has the advantages of highest efficiency over the other types of cryocooler, light weight. One of the disadvantage of Stirling cryocooler is vibration as it has two moving elements in each cylinder. This can be reduced with the help of selection of motor used for operation and hence efficient cryocooler can be made that will be helpful for large space observations for a longer period of time.
