Abstract

The geometrical aberration inherent in several different magnetic lens structures is calculated and ~ompared.Two of these satisfy our definition of a thin lens.We consider beam transport through perfect and Imperfect len.ses, and we show that beams can be compensated by adjusting the radial density distribution to match the lens aberratIon.Finally, we show that uncompensated high-current beams may become hollow through self interaction.
