Popis: Measurement of magnetic field distributions is performed using a method based on the nuclear magnetic resonance (NMR) technique of Fourier imaging. By selecting objects which limit the spatial distribution of the NMR-observable nuclei, images can be obtained which allow easy interpretation of the magnetic field distribution and facilitate rapid shimming of magnets. Results are presented showing the effect of a shim coil set of a superconducting solenoid magnet of the type use for NMR imaging. The application of this type of measurement to the rapid shimming of similar magnet designs is analysed. The effects of steel plates close to the magnet are also observed.
