- ПубликацияТолько метаданныеMultibeam biperiodic accelerating systems(2020) Shilov, V. K.; Filatov, A. N.; Novozhilov, A. E.; Шилов, Владимир Кузьмич; Филатов, Александр Николаевич; Новожилов, Александр Евгеньевич© 2020, World Academy of Research in Science and Engineering. All rights reserved.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.
- ПубликацияТолько метаданныеThe effect of the transient process on the output properties of the electron beam of a linear accelerator with a standing wave(2020) Filatov, A. N.; Shilov, V. K.; Novozhilov, A. E.; Филатов, Александр Николаевич; Шилов, Владимир Кузьмич; Новожилов, Александр Евгеньевич© 2006-2020 Asian Research Publishing Network (ARPN).The process of loading high-frequency energy into the resonator accelerating sections of a linear electron accelerator occurs with a significant time constant since the accelerating sections have a high Q factor. At the beginning of a high-frequency accelerating pulse, an accelerating electron beam lacks energy and a significant average energy bundle scatter occurs at the output of the accelerator. If one delays the electron injection pulse relative to the high-frequency accelerating pulse, then the spectrum of the electron beam can be improved and the average energy bundle scatter at the accelerator output can be reduced. Such experiments are already used for ion accelerators. This article investigates the aforementioned technique for improving the spectral properties of a beam in a two-section linear electron accelerator with a standing wave. For this, a high-frequency power system with adjustment of the high-frequency energy level in the accelerating sections is used, which can completely decouple the high-frequency generator from high Q load. Such a system can significantly improve the output properties of an electron beam. The accelerator under consideration consists of two high-Q accelerating sections based on a biperiodic decelerating structure, which are powered from a magnetron via a 3-dB bridge. The article presents the results of analytical and experimental studies.
- ПубликацияТолько метаданныеAcceptances of accelerating sections and maximum beam emittances at output of electron linear accelerators(2019) Shilov, V. K.; Filatov, A. N.; Novozhilov, A. E.; Шилов, Владимир Кузьмич; Филатов, Александр Николаевич; Новожилов, Александр Евгеньевич© BEIESP.Requirements to beam current and type of accelerated particles become more stringent in the case of application of accelerators in industry and medicine. Certain specific issues arise upon application of low energy accelerators, such as selection of efficient accelerating structure, the simplicity of fabrication, moderate cost, low occupied space, and low operation costs. Increase in beam intensity of accelerated particles only by virtue of improved acceleration and focusing has certain limits. Technical and economic performances of linear accelerators can be improved, for instance, by conversion from conventional accelerating system to a multichannel system. This article discusses the issue of the electron wiring harness in small size accelerator aimed at efficient use in industry and medicine where the facility dimensions are of high importance. Increase in beam intensity of accelerated particles by means of improvement of acceleration and focusing depends greatly on the procedure of prediction of particle dynamics. A simple procedure of prediction is proposed, the results of the study of particle dynamics in standing wave accelerators are given which confirm the possibility of maximum beam wiring harness.
- ПубликацияТолько метаданныеModified biperiodic structures for linear particle accelerators(2019) Shilov, V. K.; Filatov, A. N.; Novozhilov, A. E.; Шилов, Владимир Кузьмич; Филатов, Александр Николаевич; Новожилов, Александр Евгеньевич© 2019, World Academy of Research in Science and Engineering. All rights reserved.This article discusses the properties of modified biperiodic structures with standing wave and improved focusing properties for effective electron acceleration in linear accelerators. Main attention is paid to possible application of the focusing properties of electromagnetic accelerating field for transmission of electron beam through aperture of biperiodic decelerating system, which would reduce significantly accelerator dimensions. Predictions of particle dynamics in standing wave accelerators based on biperiodic decelerating structures are presented, which confirms possibility of the beam transmission without application of external focusing elements. The discussed procedure can be applied for designing and development of standing wave linear particle accelerators.

All rights reserved.The new linac for light ion beam injection is under development at MEPhI. Such linac was proposed for acceleration of 7.5 MeV/nucleon ion beam with A/Z=1-3.5 and current up to 5 mA for proton and 0.4 pmA for light ions. The linac general layout will include two types of ion sources: ECR ion source for proton and He ions and laser ion source for ions form Li to O. Following the LEBT ions will be bunched and accelerated to the final energy using RFQ section and 14 IH-cavities. These IH-cavities will be identical (divided into two groups) and independently phased. All cavities will operate on 81.25 MHz. Results of the beam dynamics simulations and the cavities design will be presented in the report.
- ПубликацияТолько метаданныеHigh frequency power supply to improve operation stability of linear electron accelerator(2021) Shilov, V. K.; Filatov, A. N.; Novozhilov, A. E.; Шилов, Владимир Кузьмич; Филатов, Александр Николаевич; Новожилов, Александр ЕвгеньевичThe 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.
