Résumé

The ILK Dresden designs, develops and manufactures customized non-metallic cryostats for very different applications. For the needs of a wide variety of applications both, geometrical constraints and material selection, can be realized. These cryostats are characterized by long holding time of vacuum and hence they exhibit a very long storage time of the cryogenic fluid. Not only the cryostat itself is of crucial importance to the functionality, but also the fixtures needed as a carrier for measurements inside a cryostat. Minimized thermal expansion, low vibration, maximum variability and low magnetic noise are possible features of the
cryostats. Various material-testing and experimental results are presented as well as special solutions for applications and details of construction. The following points are also discussed: Properties of a cryostat for elevated ambient temperatures of the cryostats, Geometrical limitations, Important aspects in the design of low-noise magnetic-field cryostats. Cryostats for LN2 and LHe can also be designed, manufactured, and approved for pressure applications according to the European Pressure Vessel Regulation (Pressure Equipment Directive (PED) 2014/68/EU).
