Description
X-ray irradiation offers several advantages compared to other irradiation technologies including superior penetrating quality compared to electron beams. These advantages make X-ray targets key components in a broad range of industrial applications including food irradiation, sterilization of medical devices, and non-destructive testing, among others. However, the low electron to X-ray conversion efficiency (<~10%) is a major drawback. In this talk, we will present a novel design of an X-ray conversion target based on a multicell RF structure with energy recuperation approach, promising to improve the photon yield compared to conventional X-ray targets for industrial applications. The system consists of a special RF driven target, formed by a series of accelerating cells with closed irises operating on the S-band frequency at 2856 MHz. The design incorporates a high atomic number material within the irises to generate the X-rays. We will present the rf design of the multi-cell X-ray target, Monte Carlo and beam dynamic simulation results performed to maximize the electron-to-X-ray conversion efficiency.
