In an X-rays tube, the intensity of the emitted X-rays beam is increased by

Answers (1)

The intensity of the X-ray beam depends on the number of electrons striking the target per second and in the hot-cathode tubes, this is controlled by the heater current. The wavelength depends on the voltage across the tube. The penetrating power of the X- rays is thus dependent on the accelerating voltage and the intensity of the beam on the heater voltage.

If we increase the filament current, the temperature of the filament rises and so the number of thermionic electrons emitted per second increases. This results increase in number of electrons striking the target per second and hence number of X-ray photos emitted per second increases.
