Web12 de dez. de 2024 · An electron beam at a relativistic velocity has a self-focusing effect due to the magnetic field created by the electron beam itself and the increase in electron mass, which reduces the divergence of the electron beam due to the SC effect. Therefore, the SC effect mainly occurs within the acceleration field in an electron gun.
