secondary emission การใช้

• The storage is accomplished using the principle of secondary emission.
• This design also minimized interference of secondary emission electrons dislodged from the anode.
• The elecrons can be provided by thermionic emission and / or secondary emission.
• Another random access computer memory tube based on secondary emission was the Selectron tube.
• Above another effect also starts, secondary emission.
• When any charged particle is accelerated, it emits electromagnetic radiation and secondary emissions.
• When ions strike the target, 2 3 electrons per ion are produced by secondary emission.
• When an electron hits the wall, the wall emits more electrons due to secondary emission.
• Both these methods have significant errors due to laser extinction, signal attenuation, and secondary emission
• Secondary emission had the useful feature that the rate of electron release was significantly non-linear.
• As the beam scanned the line, the phosphor was pushed well beyond the secondary emission threshold.
• This gun was set to a voltage that would cross the secondary emission threshold for the entire display.
• Secondary emission can be initiated by tearing out surface electrons from electrodes by a sufficiently high electric field.
• The continuous flow of electrons allowed the stored charge to be continuously regenerated by the secondary emission of electrons.
• Grid 4 screened this from the anode, and grid 5 was a suppressor grid to suppress secondary emission.
• Since the transitron oscillator didn't depend on secondary emission it was far more reliable than the dynatron.
• The avalanche can be triggered by any charged particle hitting the starting electrode with sufficient energy to cause secondary emission.
• Possible observable effects are missing pulses and an increase in thermal radiation due to the secondary emission from the modulator.
• The rate of secondary emission is also a function of the electron beam energy, but follows a different rate curve.
• In 1926, Philips invented a technique of adding yet another grid to combat the secondary emission that the tetrode suffered from.
