| Abstract: | The present paper deals with the thermal deformation of X ray absorber in X ray Bragg Fresnel optics. The changes of diffraction pattern and the thermal stresses in absorber caused by X ray radiation were calculated. The method and conditions about the selection of substrate material of X ray Bragg Fresnel were described, and the results about thermal deformation changing with thickness of substrate were also shown. |
