Solenoid Magnets

We integrate cryogen-free superconducting solenoid magnets up to 14 Tesla with our dilution refrigerators. On offer are many different configurations depending on your experimental requirements, e.g. incorporation of field compensated regions, increased field homogeneity, fitting of a persistent mode switch, low field drift rates and optical access.
