The paper describes the results of numerical analysis of the process of formation of an axially symmetric electron beam in an inhomogeneous electric field created by a three-electrode electron-optical system. Particular attention is focused on the creation of the electron-optical system, which has to comply with the initial requirements for systems used in the micro X-ray sources manufacturing.
Optimization calculations of the probe-forming systems with three, four and five lenses are carried out. It is shown that the proposed concept of additional power supply of the lenses allows improving the physical parameters of a scanning nuclear microprobe, which can be used in development of the new lithography methods, manufacturing of microwave and nanoelectronics devices.
The present paper concerns the modulation characteristic calculation technique development for the three-electrode electron gun. This technique is based on the analysis of the field structure made by different focusing potentials along the electron-optical system axis, which was conducted with the finite integration technique. The obtained permeability values of the first anode allowed calculating...
In the present paper the experimental and numerical methods combining for quality analyzing and determination of the optimal electron beam (EB) characteristics in TWT systems has been proposed. Potentials, which form EB with the best quality, were determined as well by experimental modeling of the operating modes of the electron gun.
The numerical calculations based on FIT-method of a three-electrode electron gun were made. Optimal potentials of the electrodes which are necessary to obtain a low-energy intensive axially symmetric electron beam were defined as well.
A method of processing and analyzing the results of the study of axially symmetric static electron beams on the transition radiation has been developed. On the basis of the received algorithms, a computer program, which allows simplifying and expediting significantly the processing of digital photos, has been compiled.
