Abstract

Thales Cryogenics is working with large effort on the extension and improvement of its full cryocooler product range for the military as well as the civil market. Due to improvements made in the last few years by most cooler manufacturers, cryocoolers are - in the defense world - more and more seen as a commodity. However, the requirements under which cryocoolers are used and the demands which users are requesting from a cryocooler such as increased reliability, shorter cooldown times, higher efficiency, lower induced vibrations and decrease in size and mass are still very challenging. With as basis his wide product portfolio Thales Cryogenics has worked extensively on the extensions and improvement of its RM cooler range and to improve the CDT and robustness of its LSF cooler range for even more stringent environmental conditions. Next to the coolers also the latest control electronics of Thales for its linear drive coolers will be presented. Apart from Stirling coolers Thales Cryogenics is also manufacturing pulse tube coolers. At present these coolers are mainly used in civil applications. Although the CDT and efficiency of pulse tube coolers are still lower compared to Stirling coolers the reduced vibration level and increased robustness of the cold finger could be beneficial for future developments with respect to sensor cooling. This paper presents the latest results of the work performed at Thales and explains the gain for the users of cryocoolers.
