Polychromatic X-ray source for diffraction apparatus using _polychromatic X-rays |
| abstract |
There is provided polychromatic X-ray source used in a polychromatic X-ray diffraction apparatus, in which polychromatic X-rays are cast upon a sample to be analyzed, the energies of the X-rays diffracted from the crystallographic planes of the sample are measured and the physical properties of the sample are detected on the basis of the measured energies. The polychromatic X-ray source has a container made of radiation shielding material and having an X-ray outlet channel and the container contains therein a radionuclide for emitting radioactive rays and a substance for scattering and absorbing the radioactive rays emitted from the substance so as to obtain polychromatic X-rays. The polychromatic X-rays emitted from the substance travel through the X-ray outlet channel and are then made parallel through a Soller slit to be cast upon the sample. A slide door is provided in the channel so as to block the polychromatic X-rays if necessary. |
