Quantitative simulation of electron beam’s focal spot in thermionic emission
The focal spot size of an electron beam in x-ray photography lamps, which is formed on the anode, has an important effect on the contrast of x-ray images. Usually, the grid is used in x-ray production lamps only to stop or regulate the current of the electron beam, but its effect on the dimensions a...
