© 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.
