ABSTRACT:
A method of measuring an accelerating voltage applied to an x-ray source to produce x-rays includes applying an accelerating voltage to an x-ray source to produce x-ray radiation having an axis; diffracting first and second portions of the x-ray radiation that are symmetrically disposed relative to an axis with a body of a single crystal material having a curved surface symmetrically curved relative to a central axis of the x-rays to produce two spectra of the x-ray radiation, each spectrum including continuous x-ray radiation having an end point energy at the maximum energy of the x-ray radiation; forming an image of the spectra of the x-ray radiation including respective end point energies; and measuring the separation of the respective end point energies of the spectra of the image and, thereby, determining the accelerating voltage applied to the x-ray source.
