Abstract :
A fast and reliable 2D optimisation technique for smooth shimming of magnet pole faces is presented. It has a physical basis and always yields a solution with shims that provide high field matching over a wide range of excitation. The OPTIMA code has been developed to automate the optimisation process. It is easily modified to different types of magnets for a variety of applications. It has been proved as a very valuable tool in the process of designing dipole, quadrupole, sextupole and combined function magnets for the Swiss Light Source (SLS) at the Paul Scherrer Institute (PSI).
