Special Issue Information
Dear Colleagues,
The electron beam is the foundation of modern electronic technology, and its applications can be seen everywhere in our daily life. With the development of technology, the trend of the electron beam has moved towards higher power and higher energy. Related technologies are widely used in microwave tubes, accelerators, vacuum displays, materials processing technologies, ion beam devices, electron beam lithography, etc. However, the generation, formation, and transportation of high-power/high-energy beams are a challenge for researchers. Combining our professional fields and promoting technology development, this Special Issue "New Challenges in Electron Beams" mainly introduces the latest progress and applications of high-power electron beams in various vacuum electron devices (VEDs), including the gyrotron, gyro-traveling-wave tube, traveling-wave tube, klystron, backward wave oscillator, series sheet beam devices, pseudospark, etc. The purpose of this Special Issue is to attract novel and advanced research work related to the design, experimental implementation, and application of high-power electron beams. We also welcome manuscripts on the integration of high-power electron beams in other fields.
The scope of this Special Issue incorporates a wide range of topics on electron beams and their applications, including, but not limited to, the following:
- Novel electron gun design for various vacuum electron devices;
- Electron emission theory, material, and cathode investigation;
- Phenomenon investigation for breakdown, ionization, and halo in the electron beam generation and transportation processes;
- Thermal analysis for high-power electron optics systems;
- Applications such as accelerators, vacuum displays, materials processing technologies, electron beam lithography, etc.;
- Related interdisciplinary technologies to improve current electron beam performance or extend the application scope.

Title: The Movement Mode of the Microworld Particle
Authors: Jinhai Li
Affiliation: Engineering Research Center of Nuclear Technology Application, Jiangxi Province Key Laboratory of Nuclear Physics and Technology, East China University of Technology
Abstract: Most physicists are dissatisfied with the current explanation of quantum mechanics, and the movement of the microscopic particles always confuses most physicists. Lots of people want to find a method to solve this question. However this question cannot be solved perfectly up to now. In this paper, the annihilation generation movement (AGM) is developed according to the electron motion in hydrogen atom. To verify the AGM, a curved surface to fit the dark fringe of the single slit diffraction is proposed. Based on the AGM, the wave function of a free electron is rewritten and the double-slit experiment can be understood. Here, we show the AGM is a perfect physical image to solve the puzzles of quantum mechanics, such as the understanding of Heisenberg's uncertainty principle and the steady-state transition. We anticipate that we can find a new way to explain the quantum mechanics based on the AGM.
