| 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.
