I KVp and number of x-rays

  1. May 23, 2016 #1
    Why does increasing the kVp in x-ray production increase the number of x-ray photons if the number of electrons produced by the cathode is unchanged? thanks

    i think the increase in tube voltage accelerates the electrons to higher energy and radiation from accelerated/decelerated charge "Bremsstrahlung" increases thus increasing the x-ray intensity/number of photons-these radiations are of continuous nature and fall in the range of continuous x-rays. however the characteristic x-rays which are characteristic of the target -also increases in intensity as number of transitions increases - hardly one percent of the energy input gets out as x-rays.
