Diode system with the thin field emitter modelling in cylindrical coordinates

In this graduate qualification work Kalaturskoy E.V. an axisymmetric diode electron-optical system based on field emitter in a cylindrical coordinate system is simulated. The field emitter in the form of a thin filament of finite length is located on the left flat end of the cylinder. The anode is the right flat end of the cylinder. Kalaturskaya E.V. successfully solved the problem. As a result, the electrostatic potential distribution was found in a analytical form - in the form of Fourier-Bessel series in the whole area of the system under investigation. The coefficients of Fourier-Bessel series are the solution of the system of linear equations with constant coefficients.

The program was written in C ++, and Kalaturskaya E.V.  presented the results of numerical calculations of the electrostatic potential distribution for specific diode systems.
