Topic : Development of high field gradient accelerating structure for industrial applications

  

 Scope  

                        The industrial application is one of the key applications of electron linear accelerators. An accelerating part is the most crucial component of an electron linear accelerator in order to increase energy of the electrons up to 10 MeV with high current. In design and development of a high field gradient in normal conducting linear structures is a key issue in physics research and other applications at high energy electron. One of the important effects that occurs during deliver a high RF power into the linear accelerator is RF breakdown leading to limitations on acceleration and performance of the accelerator. This research focuses on the physical and engineering design of the high-gradient accelerating structure section without RF breakdown phenomena. These phenomena also require a detailed study on the dedicated developed systems. The design and simulation of the linear accelerator frequently use tool codes to perform physics and engineering results as CST-MWS, ASTRA, Pamela which are used to model electromagnetic field for acceleration in the accelerator structure and follow all electron trajectories in these fields to achieve a right mode of acceleration The thermal analysis and the vacuum performance are studied as well with ANSYS. In order to guarantee with achieving a high-performance of high-field gradient linear accelerator, the beam dynamics of the electron beam are studied and simulated by using particle accelerator codes.
