11. For general surface characterization, the electron gun is operated the range of 10-30 keV. 12. Taken in high vacuum using an electron gun with an energy of 94 eV. 13. But what is the difference between beta particles and electrons from an'electron gun '. 14. An electron gun generates an electron beam that is interacting with a slow-wave structure. 15. The electrons are fired into one end of the tube by an electron gun . 16. The magnetic plate and the other components are the equivalent of an electron gun assembly. 17. Early Telechrome devices used two electron guns aimed at either side of a phosphor plate. 18. Three separate electron guns are individually focussed on the mask, sweeping the screen as normal. 19. Telechrome used two electron guns aimed at either side of a thin, semi-transparent mica sheet. 20. The basic concept uses a conventional CRT layout but with two sets of electron guns .
