X=ray spectrometer with filter system - has electron gun of radioactive isotope and selected filter to measure rays between sample and collimator

摘要

Energy X-ray spectrometer is complete with X-ray source (1), a test picture, a collimator (10) an integrated circuit detector and a pulse height detector. A filter (5) is positioned to measure the rays and is selected according to the test being carried out. A range of single and multiple filters made of materials Indium, Cd, Ag, Thallium, Hg, Pt, Iridium and gold are used to detect Hg, Thallium, Zn and Pb. A secondary source consists of Xe, Caesium, Ba, La, Cer, praseodymium or Nd. The electron gun is made from a radioactive isotope and the filter is fitted between the sample (7) and the collimator (10).
