- Abstract
A Large heat lift Pulse Tube Cooler (LPTC) is currently under development in partnership between AIR LIQUIDE/DTA, CEA/SBT and THALES Cryogenics. This work is funded by the European Space Agency in the frame of the Earth Observation Future Programmes. The pulse tube foreseen performance is to provide a cooling power of 2 W at 50 K with 10°C ambient temperature and 140 watts maximal electrical input power to the motors of the compressor. A development model (DM) has been manufactured with an in-line architecture for the Pulse Tube cold finger connected to an off-the-shelf compressor from Thales Cryogenics. The development phase will be presented as well as the various trade-offs that have been performed, both on the cold finger and compressor side, to cope with the thermal, mechanical and electrical environmental specifications. The impact of the matching between compressor and Pulse Tube cold finger and the results of the DM test campaign will also be discussed. The next development phases leading to the Engineering Model delivery to ESA/ESTEC in September 2006 will also be presented.
