Webwar Cooler Assembly (DDCA), which is a vacuum chamber closed by a window. A cold shield and a cold diaphragm limit the angle of view of the IRFPA, in order to avoid background emission from the external roof of the Dewar at ambient tem-perature. Our work aims at miniaturizing optical systems as- WebAug 1, 2014 · In the present study a finite-element analysis of a Dewar-Detector-Cooler Assembly (DDCA) with a J–T cryocooler is developed and implemented using the Ansys™ code. The model is axisymmetric; thus, the Dewar-Detector Assembly (DDA) is fully simulated and its heat transfer is calculated directly.
