In cryogenic environments special care needs to be taken when choosing the right RF components. In NMR, for example, cryoprobes can be cooled at 20 K or lower temperatures.
The various thermal expansion coefficients of metal and dielectrics are a special challenge to assemblies in a cryogenic environment. This is the area of use for semi-rigid cable assemblies or the Cobraflex cable specially developed for this application.
Ventilated connectors and adapters
Special ventilated connectors from HUBER+SUHNER reduce the negative effects of outgassing during cooling cycles. Most standard components can be supplied in a ventilated version.
