Stainless steel-Materials and Magnetic Properties
Electric fields generated across the opposing deflection plates of the electron gun system optics exert a force on the negative charges in the electron beam, causing an acceleration perpendicular to their original path, with the electron deflecting away from the negatively charged plate. The magnitude of this acceleration depends on 1) the strength of the electric field (the voltage across the plates, separation distance of the plates), 2) the mass and velocity of the particle, 3) plate geometry, and 4) the dielectric of the material present between the plates (in this case, vacuum).By manipulating the electric field across the deflection plates, the trajectory of the electronbeam can be altered to direct it at specific targets or to raster it in various pre-determined patterns.
