PURPOSE:To measure the energy of scattering X-rays by Compton-scattering gamma rays into the radiation route or gamma rays from isotope to radiation port. CONSTITUTION:A reflector 15 is made of, e.g., lead, and its focus is formed on the curved face which is on the line connecting Soller slits 13 and isotope 8 and aligns to the isotope 8. Hence, the incident angle of the gamma rays radiated from the isotope 8 to the foregoing reflector 15 becomes no longer constant and therefore the gamma rays become the X rays to create parallel beams heading toward the Soller slit 13 side after Compton scattering and the X rays become the ones which have been turned to white X-rays by assuming various energy values. And the X rays are perfectly paralleled by the Soller slits 13 and will then be radiated to the measuring object T. |
