Mr Thierry Trollier (Absolut System)


Absolut System has built a 30K and a 10 K remote Helium cooling loops used as vibration free cooling source, respectively for IR detectors electro-optical characterization test bench and two-stage optical cryostat.

The circulation loops are based on a by-passed flowrate from either a two-stage Gifford–MacMahon cryocooler or a two-stage Pulse Tube cryocooler. Dedicated compact and high efficiency tubes & shell heat exchangers have been designed and produced for the recuperators.

The paper describes the design and the performances of the vibration free cooling system produced. The current work towards a 4K vibration cooling source and its coupling with a subK stage will be introduced as well.
