edge between the and lines of the incident photon beam, this other Kα Kβ substance can be used to significantly reduce the intensity of the Kβ line relative to the The absorption edges of elements with Kα line. Z Filter = ZTarget - 1 (or - 2) meet this requirement. The thickness of the filtering material is usually chosen to reduce the intensity of the Kβ line by a factor of 100 while reducing the intensity of the line by a factor Kα of 10 or less .the propose from filter to absorb the component much Kβ more strongly than component ,because of the abrupt change in its Kα absorption coefficient between two wavelengths . Lec. No. (8) Production of x-rays x-ray tube: any x-ray tube must contain : 1)a source of electrons . 2)high accelerating voltage. 3)metal target. The most of kinetic energy of the electrons is converted into heat in the target ,and must be cooled by water to prevent its melting. x-ray tubes can be divided into two types according to provide electrons :
