WebDec 12, 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. WebAt high bias, the electrons are repelled toward the filament and the emission current and brightness decrease to zero. Thus, for each instrument, there is an optimum bias setting for maximum brightness.
