Auteurs : TROLLIER T., TANCHON J., BUQUET J., et al.

Résumé

Air Liquide Advanced Technology Division proposes two pulse tube cooler systems in the 40-80 K temperature range. The miniature and the large pulse tube cooler qualification and production status are presented. The integration of such pulse tube cooler systems in upcoming Earth Observation missions such as Meteosat Third Generation, Sentinel 3, etc., is discussed. The associated cooler drive electronics (CDE) is also an important aspect specifically regarding the active control of the cryocooler during the launch phase and the active reduction of the vibrations induced by the compressor. The CDE design description is presented and, in particular, the FPGA-based solution is discussed.
