In this system a low-energy scanning beam was used, and magnets were set to cause the electrons to strike the sides of the multipliers.
When the electrons strike the phosphor, the phosphor "lights up" at that location for a time, and then fades away.
At very low energies, electrons from the gun will strike the phosphor and nothing will happen.
These electrons move along the Earth's magnetic field and eventually strike the Earth's ionosphere, causing the x-ray emissions.
In any tube, electrons strike the anode with sufficient energy to cause the emission of electrons from its surface.
The electrons strike the object, are scattered, detected and then converted into an image.
Far too often the electrons strike the grid, causing energy loss.
The screen is bright enough at these lower voltages because the viewer watches from the side that the electrons strike the phosphor.
When the fast-moving electrons strike phosphor on the back of the screen, light is produced.
That improves the image quality when the electrons strike the screen.
