[en] Activities at the Dresden Institute of Air Handling and Refrigeration include the design, development and manufacture of individual, nonmetallic cryostats for a variety of applications. These cryostats are distinguished by their optimized inner design as well as their long vacuum life, this permitting an extremely long service life of the cryogenic medium. These cryostats are designed and manufactured such that they function independent of their spatial orientation, permitting their use in any desired assembly or structure. This paper describes special solutions for specific applications, including details on design, various material analysis methods and the results of thermodynamic measurements. It also presents a newly developed low-noise, nonmetallic helium cryostat that works independent of its spatial orientation as well as new cryostat solutions for high-temperature superconduction applications such as current limiters, torque motors and generators. Analyses on susceptibility and residual magnetisation were carried out in cooperation with PTB Berlin with a view to verifying whether the aimed-for low level of magnetic noise had been achieved.
