21. A CRT monitor gets its illumination from three electron guns firing at the phosphor-coated glass screen. 22. The electron gun is one of the most important piece of equipment in a RHEED system. 23. They took a Sutton tube and disconnected the electron gun and reflector, leaving just the cavity. 24. "An electron is accelerated through an electron gun . 25. Systematic setup of the electron gun , sample and detector / CCD components of a RHEED system. 26. The electron beam is generated by a device similar to the electron gun in a TV set. 27. A CRT with two electron guns , one for reading and one for writing, made this process trivial. 28. In television sets and computer monitors, something analogous happens when electron guns fire beams that illuminate screens. 29. They cleverly implemented a single electron gun with three independent cathodes, all of which greatly simplified convergence. 30. The figure below displays commercial examples of thermionic emitters and electron guns produced at Heatwave Labs Inc.
