Formation of a homogeneous magnetic field in spectrometer dipole magnet using permanent magnet

Problems of obtaining a homogeneous magnetic field in a spectrometer magnet are considered. The 0.15-T magnetic field in a 57-mm gap is produced by means of permanent SmCo/sub 5/ magnets. Results of calculations and measurements of the magnetic field are presented. On the basis of these results the dimensions and location of ferromagnetic shunts, correcting the magnetic field, have been calculated.<
