Computer Method for the Analysis of Axisymmetrical Magnetic Fields for an Accelerator

A computer code has been set up for use in calculating the magnetic field distribution for a circulator accelerator. The code calculates axisymmetrical three-dimensional magnetostatic fields, including the effect of coil current distribution. The modified scalar potential for axisymmetrical fields is derived to solve the boundary value problem of Poisson´s equation. Magnetic fields for betatron poles have been computed. The results are in agreement with meas - urements.
