Abstract
A new version of the charge-density method, applicable to the analysis of the potential distribution in multi-element electrostatic lenses used for focusing beams of charged particles, is presented. A study of the optical properties of a four-cylinder lens has been carried out. Data are given for this lens over a wide range of the voltages applied to the electrodes.Keywords
