Question

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

Answer 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.
