Abstract
Long wavelength IR detectors need to be cooled at cryogenic temperature to achieve high performances. This specific need makes it difficult to integrate the detector because of high cost of dewar and cooling device designed to fulfill severe vibration conditions. A new era for IR detection could begin with flat structures allowing intrinsic vibration resistance for detectors to be plugged on electronics board. Sofradir has carried out a study about feasibility of detector dewar assembly including a flat Joule-Thomson cooler with porous heat exchanger in cooperation with Air Liquide. The aim of this paper is to put forward the interest of such a product. The very good results achieved demonstrate a promising future for such flat structure detector assembly.
