An Induction-Coil Measurement System for Normal- and Superconducting Solenoids

The magnetic measurement of solenoids relies on different methods to characterize the field quality and locate axis. Usually, Hall mappers stretched-wire systems are used for these tasks. This paper presents an alternative, fluxmetric method measure radial dependence axis with a single instrument. solenoidal-field transducer is based disc-shaped induction-coil array concentric coils 90 deg. arc segments mounted translation stage. allows sample magnet along its extract both longitudinal transversal components. design, development, validation new instrument described. induction coil, which core this instrument, fabricated in printed-circuit board technology, has become standard applications. Results recent measurements normal-conducting solenoid given.
