Green phosphor screen
WebA cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen. The images may represent … WebFor a green phosphor, this means that a single 20keV electron will produce well over 1000 photons, and a 5keV electron well over 250 photons (the phosphor response remains linear down to low energies). The phosphor is actually a pretty efficient transducer.
