MODELING AND OPTIMIZATION CODES FOR MASS-SEPARATOR DESIGN

In this report we suggest an approach to design optimal mass-separators. In the beginning for linear approximation we build some hypersurfaces in the corresponding parameters space, described desired characteristics. For this purpose we use computer algebra codes with necessary visualization procedures. Particularly, for solenoids as focusing elements these hypersurfaces demonstrated a very complicated behaviour. Secondly, we investigate found optimal regimes in allowed domains in the parameters space including nonlinear aberrations both for separate elements and for total beam line. Such approach should lead to a better understanding of the influence of different parameters in charged particle optical systems. The corresponding computer codes demonstrate effectiveness of this approach.
