The objective of this activity is to develop, build and test a Breadboard of a miniaturized very high fequency Pulse Tube cooler that can suit the needs of Earth Observation missions. More specifically small sized SWIR/MWIR to TIRmissions that require cooling in the 77K to 120K temperature range. The main key requirements are summarised hereafter:-Mass: < 750g-Cooling Power at 25W input Power and 20degC I/F Temperature: 2W@120K-Cooling Power at 25W input Power and 20degC I/F Temperature: 1W@77K-Driving Frequency: > 90Hz-Exported Microvibrations in piston axis (all harmonics, assuming compensation): <0.1N-Exported Microvibrations in transverse axis (all harmonics): <0.25N-Minimum operational temperature at -73degCThis project being part of the Technology Development Element, innovation is encouraged. Considering the potential markets that a miniaturised cooler could appeal to (e.g. New Space) a certaindegree of design to cost is recommended.Note: Considering the fact that one of the driving innovation of the item to be developedis the form factor/miniaturization which is difficult to be breadboarded, it is expected that at least part of the system (e.g. compressor) will almost be at Engineering Model level.
