“…Efficiency of standing wave linac can be increased by multibeam accelerating systems. Their optimum operation can be provided only by focusing by electromagnetic eigenfield [11,12]. In addition, it is possible to improve focusing properties of accelerating systems of standing wave linac by modification of shape of accelerating cells, which provides better implementation of focusing capabilities of both radial component of electric field and azimuthal component of magnetic field.…”

This article discusses the issue of increase in intensity of electron flow in small-size accelerator for efficient application in industry, medicine, and other fields of science and engineering, where the sizes of unit are important. A possible approach to solve this problem is to combine acceleration and focusing of flow of charged particles in a single structure. Comparison of various types of accelerating structures demonstrates that at injection voltages not higher than 100 kV, the most preferred are biperiodic decelerating structures. Since the increase in intensity of beams of accelerated particles only by improvement of acceleration and focusing has certain limits, then it is proposed to improve technical and economic specifications of accelerator by conversion from regular accelerating system to multichannel design. Transportation and focusing of beams in multibeam structures, which significantly improve acceleration efficiency without noticeable increase in transversal sizes of radiating unit, seems to be possible only by means of high frequency focusing.

“…Steady radial motion of particles in standing wave accelerator with high-frequency (HF) focusing is possible only in the phase region where energy gain is not maximum [10]. It is reasonable to implement HF focusing mode in accelerating structures with high shunt resistance in order to preserve high rate of energy gain by electrons over total accelerator length.…”

This article discusses possibility of harness wiring with the use of focusing system of high frequency eigenfields of accelerating resonators in standing wave linear accelerators on the basis of biperiodic slowing systems. The scopes of business activities and specificity of existing engineering processes applied in industry, especially in chemistry and metallurgy, require for special measures on environmental protection. At present electron linear accelerators operating in pulse mode are used for application purposes. Such accelerators can be characterized by sufficient beam power for efficient industrial use and for environmental protection. The results of numerical analysis of electron dynamics in two-section accelerator upon various initial conditions are presented. The obtained results are applied for development of actual accelerator, calculated and experimental data are given. The performed experimental study confirmed possibility of development of standing wave linear accelerator without external magnetic focusing system with output beam diameter of not higher than . The results of calculations of beam dynamics are experimentally verified.

“…If the function of distribution of electric field intensity along the axis of standing wave linac is considered at certain time, then it can be seen that it is comprised of alternated pulses of different polarity with spatial period equaling to the generator wavelength (Novozhilov, Filatov, Shilov, 2015). The most promising in standing wave linac is focusing upon which beam transmission is based on focusing action of the electromagnetic field itself (Fainberg, 1962).…”

The use of linear electron accelerators in medicine and industry is explained by the simplicity of the input and output of accelerated electrons and adjusting the energy and dose rate, as well as the high dose rate of bremsstrahlung. The purpose of this work is to increase the stability of their work. A standing wave accelerator containing a high-frequency generator, a phase shifter, a waveguide bridge, a high-frequency load, and an accelerating system of two accelerating sections is equipped with two waveguide tees. Their inputs are connected to the output arms of the waveguide bridge, and the first and second output arms of each tee are connected to the first and last accelerating cells of each section, respectively. In this system, due to the introduction of several elements that do not require large costs for manufacturing and tuning, a significantly greater frequency separation of the operating mode of oscillations from neighboring ones is ensured, or even a single-frequency excitation mode is implemented, which makes it possible to significantly increase the stability of the accelerator operation. This technique can be used to increase the stability of operation in the design and calculation of linear accelerators of electrons with a standing wave.
