Résumé

In the framework of a Research and Technology program co-funded by the French space agency (CNES), CEA/SBT is developing a high-frequency, two-stage pulse tube cold finger able to provide 2 W at 70 K on the second stage and simultaneously 6 W at 140 K on the first stage. This cooler is addressed to the cooling needs of detectors for low-Earth-orbit observation missions. To capitalize on other European efforts in the cryocooler field, this cold finger is designed to operate with the compressor developed under the ESA LPTC project. This compressor is able to provide around 120 W of PV power. A modular prototype of the pulse tube cold finger has been built, and the design of this prototype is presented together with our first experimental results. The effect of input power and rejection temperature is described.
