Pulse-tube cryocooler for integrated detector dewar cooler assembly

Thales Cryogenics presents a new product in its portfolio, the LPT9511 pulse-tube cooler. This cooler is part of the High-Availability product range at Thales Cryogenics. The new product development was aimed specifically at IDDCA applications, combining the extreme reliability of pulse-tube coolers, 99% reliability after 10 years of continuous use, with the ease of integration and standardization typically seen in infrared applications. In previous conferences, the design concepts and principles have been presented. Since then, the design has been optimized for improved performance and robustness. Also, additional interfacing materials are now available. In this paper, the status of the design and qualification of the final product will be presented.
