| 11. | As the beam scanned the line, the phosphor was pushed well beyond the secondary emission threshold.
|
| 12. | This gun was set to a voltage that would cross the secondary emission threshold for the entire display.
|
| 13. | Secondary emission can be initiated by tearing out surface electrons from electrodes by a sufficiently high electric field.
|
| 14. | The continuous flow of electrons allowed the stored charge to be continuously regenerated by the secondary emission of electrons.
|
| 15. | Grid 4 screened this from the anode, and grid 5 was a suppressor grid to suppress secondary emission.
|
| 16. | Since the transitron oscillator didn't depend on secondary emission it was far more reliable than the dynatron.
|
| 17. | The avalanche can be triggered by any charged particle hitting the starting electrode with sufficient energy to cause secondary emission.
|
| 18. | Possible observable effects are missing pulses and an increase in thermal radiation due to the secondary emission from the modulator.
|
| 19. | The rate of secondary emission is also a function of the electron beam energy, but follows a different rate curve.
|
| 20. | In 1926, Philips invented a technique of adding yet another grid to combat the secondary emission that the tetrode suffered from.
