- Abstract
- This paper describes some analytic approaches to describe the fringe fields of flat and cylindrical capacitor. The paths of the particles are found by way of the numerical decision of the differential Lagranzh's equations, in which electrostatic potential and power function are used as generalised coordinates. A method for the calculation of deflection of charged particles from the axis is developed. The behavior of a charged particle beam in a flat capacitor is approximated by using a sharp cut-off boundary for the field, which has the provision of taking fringe fields into account. It is shown that fringe fields enlarge the deflection and perfect the focusing the beams of the charged particles.
