Abstract
The RMs1 is the new SWaP rotary cooler qualified by Thales in 2018. The architecture and the building blocks used to design that cooler have led to significant improved efficiency. The paper will describe the performances of the product, especially its thermal efficiency. An updated presentation of the reliability figures will also be done. The current available cryogenics power and the thermal efficiency allow RMs1 to be used for a wide range of applications. Either large detector arrays could be cooled by an RMs1 at High Operating Temperature, either smaller dies could be cooled down to lower temperature. The presentation will focus on the associated tuning of some parameters like the filling pressure to find the best trade-off adapted to the application. For instance, 24/7 applications will focus on reliability while HHTI may be more concerned by the power consumption. Also a first reflection will be presented on the potential definition and performance of a splitted RMs1 cooler where the cold fingers is detached from the compressor enabling a more flexible integration with a significantly reduced length in the axis of the cold finger. As a result, a mapping of cryogenics performances will be presented.
