Description
The progressive replacement of radioactive sources is stimulating growing interest in compact linear accelerators, which are better suited for field deployment. Such systems must emphasize modularity, transportability, and, above all, reliable performance under operational conditions.
This work introduces a family of compact X-band linear accelerators designed to produce electron beams in the low-MeV energy. The engineering design focuses on the key component: the accelerator structure. A biperiodic on-axis coupled standing-wave structure was selected, operating in $\pi/2$ mode.
Simulation results demonstrate that the proposed configurations achieve the targeted energy levels with controlled beam transmission, while providing a focal spot size (FWHM) below 1 mm, significantly outperforming conventional radioactive sources ($\approx 5$ mm).
This paper summarizes the overall design approach, highlights the main simulation results, and outlines the current progress of development activities.
