An analytical-numerical calculation method for the shaping of an axial-symmetrical and radial-inhomogeneous magnetic field is introduced. The shaping calculation of the radial inhomogeneous magnetic field for a

He mass spectrometer was completed by using this method
and the deviations of the real magnetic field from the desired one are less than 1×10
