Paper Abstract

AL/DTA became a major supplier in the field of space cryogenics for the European Space Industry. From MELFI freezer for the International Space Station (ISS) to HERSCHEL and PLANCK satellites for Cosmic Vision, AL/DTA has acquired a large know-how in space cryogenic systems. Convinced by the great interest of Pulse Tube technology for space applications and especially for Earth Observation or Surveillance Tracking, AL/DTA started its first development in mid nineteenths. Then the European Space Agency started to support the development in 2000. Partnerships were launched with CEA/SBT (France) and Thales Cryogenics B.V. (The Netherlands) in order to take the advantage of the competencies and experience of each other. Based on the will to improve important issues such as reliability and mechanical robustness, technology improvements are now available in AL/DTA Pulse Tube coolers. This paper proposes an overview of AL/DTA cryocoolers for space applications following by a detailed description of Pulse Tube Coolers and particularly their integration.
