Abstract :
Some results of optimization of NdFeB hexapole parameters, carried out on the basis of analytical and numerical calculations for a 14 GHz compact ECR ion source are presented. On providing the required value and distribution of magnetic field it has been possible to minimize the magnetized volume of the hexapole. The number of bars and outer radii of the Halback hexapole magnetic rings at a fixed inner radius, defined by the outer radius of the plasma chamber, have been varied
