Abstract

This thesis is concerned only with certain types of electrostatic lenses, which are used to understand the nature of the focusing of an ion beam in the range of energies from 50 to 250 kev.Only systems which are axially symmetric, as well as electrostatic fields, will be focused on in this study. Also, comparisons will be frequently made and references given, as possible aids in the event a new accelerator should need to be designed.

This paper is divided into four parts.The first part is concerned with the general theory of ion or electron optics.The second part of the paper considers the focusing properties of the source element, the initial focusing system, and the high voltage section.In the third part, the accelerator as a whole is discussed, and comparisons between experimental and theoretical results are made.The last part considers miscellaneous focusing problems.In the particular, the focusing of low energy ions is discussed, where the problems involved are indicated and possible solutions are given.
