Respuesta :
Suppose that the collector is held at a small negative voltage with respect to the grid. Yes, accelerated electrons reach the collecting plate but only those electrons with energy less than the potential difference established between the grid and the collector will reach the collector.
Those electrons with energy greater than the potential difference established between the grid and the collector will reach the collector.
What happens when an electron is accelerated in a uniform field?
A uniform transverse magnetic field encounters a force F as it travels through an electron that has been accelerated by a potential difference V. The electron in the same magnetic field will feel a force if the accelerating potential is raised to 2V.
What happens when accelerated electrons strike a target material?
Accelerated electrons can interact with a target material and produce a desired chemical reaction when they strike it. Accelerated electrons, however, might also pass through the substrate due to their high speed and kinetic energy.
How does an electron beam accelerator's beam current function?
Being entirely electrical, an electron beam accelerator's beam current and driving systems can be electrically interconnected. The substrate exposure level would remain constant as web speed increased since an increase in beam current would follow suit.
