Method to produce an uniform magnetic field in a dilution refrigerator

Abstract

Development of superconducting chips often requires an extended region with a highly uniform magnetic field. Frequently used for such a purpose Helmholtz, solenoid and Maxwell coils produce a limited volume where magnetic field is uniform. The report suggests a method for calculating a multi-coil device with the maximum value of equilibrium field. An influence of manufacturing tolerance is discussed. © Published under licence by IOP Publishing Ltd.
