A linear accelerator system according to an embodiment is for generating an MeV electron beam. The linear accelerator system includes a linear accelerator cavity having an enclosure, wherein the enclosure is open at one end to provide an exit port for the MeV electron beam; and a switchable magnet unit designed to, in a deflection mode, generate a magnetic field within the linear accelerator cavity to enable at least one electron, emitted within the linear accelerator cavity, to interact with the enclosure due to deflection away from the exit port caused by the magnetic field. Accordingly, in an embodiment, in the deflection mode, an intensity of the MeV electron beam passing through the exit port is relatively lower than an intensity of the MeV electron beam passing through the exit port in a beam generation mode of the switchable magnet unit.
