An electron accelerator is provided. The electron accelerator comprises a resonant cavity comprising a hollow closed conductor, an electron source configured to inject a beam of electrons, and an RF system. The electron accelerator further comprises a magnet unit, comprising a deflecting magnet. The deflecting magnet is configured to generate a magnetic field in a deflecting chamber in fluid communication with the resonant cavity by a deflecting window. The magnetic field is configured to deflect an electron beam emerging out of the resonant cavity through the deflecting window along a first radial trajectory in the mid-plane (Pm) and to redirect the electron beam into the resonant cavity through the deflecting window towards the central axis along a second radial trajectory. The deflecting magnet is composed of first and second permanent magnets positioned on either side of the mid-plane (Pm).

An electron accelerator comprising a resonant cavity, an electron source, an RF system, and at least one magnet unit is provided. The resonant cavity further comprises a hollow closed conductor and the electron source is configured to radially inject a beam of electrons into the cavity. The RF system is configured to generate an electric field to accelerate the electrons along radial trajectories. The at least one magnet unit further comprises a deflecting magnet configured to generate a magnetic field that deflects an electron beam emerging out of the resonant cavity along a first radial trajectory and redirects the electron beam into the resonant cavity along a second radial trajectory. The resonant cavity further comprises a first half shell, a second half shell, and a central ring element.
