Paper Abstract

To give an answer to the potential demand of low cost integrated dewar cooler assembly (IDCA) devoted to CMT Infra Red detectors with a cut-off wavelength in a 3 - 5 micrometers bandwidth cooled at intermediate cooling temperature (i.e. 140 - 200 K), small, efficient and reliable coolers with affordable price are required. A comparison between different cooling concept like lightweight IDCA Stirling and Pulse Tube, active Joule Thomson and thermoelectric is done. This comparison is made with respect to the efficiency, reliability and cost for a cooling power objective of 500 mW at 140 K and 23 degree(s)C ambient.
