The present paper illustrates a case study in the progress of ongoing research work to develope a 100 litre Helium cryostat with in-situ recondensing facility.The cryostat with a cryocooler sock comprises of 46 components assembled in an optimal sequence. Cryostat development involved thermal load estimation, mechanical design, fabrication of components and sub-assemblies. The cryostat deploys...
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...
This paper will present the methodology developed by Absolut System for the design and optimization of high capacity cryopumps required for the testing and qualification of electrical propulsion thrusters.
Design, production and tests of a complete test chamber will be presented, including the LN2 feed thermal shrouds and the cold traps thermally anchored to a single stage AL230 type...
In the last 20 years, 2-stage cryocoolers have been found to provide an optimum solution for a wide range of applications like low temperature physics, superconducting cold electronics, cryopumping and superconducting magnets. For a proper design of helium cryostats with significant cold masses connected to the first and second stages of cryocoolers, it is important to have a load map (also...
AFCryo is a joint venture company between Fabrum Solutions, of New Zealand, and Absolut System, of France specialising in the development and delivery of cryogenic equipment utilising patented membrane cryocooler technology.
A commercial product range has been developed over the last 5 years using an innovative concept of a metallic membrane Pressure Wave Generator (PWG) patented by Callaghan...
