Paper Abstract

The static mass-analyzer with in-homogeneous field and the cylindrical poles suggested by authors earlier has been investigated theoretically when the angle pole sizes were varied in big diapasons. The analytical expression of the magnetic scalar potential distribution has been obtained. The main parameters in the dispersion plane have been found for first order angular focusing when the beam trajectories have three turns. The operating conditions with the space focusing have been found too. The optimal angle pole sizes have been given from point of view of the maximum specific mass dispersion. The comparison with the mass-analyzers with the homogeneous field has been made.
