X-rays: Typical diagnostic wavelength and photon energy range. - 100ev-200 keV min. wavelength 6pm-12nm Structure and function of the x-ray tube. - A vacuum tube with an anode and a cathode. The cathode is heated and electrons are emitted, they are accelerated by a voltage difference in the tube. When the "brake" against the material of the anode, they release their high kinetic energy in the form of an x-ray. *x-ray tubes are of very low efficiency, most of the radiation is dissipated as ...
