Time-Saving Measurement of X-Ray Spectra for Self-Rectified Generators.

Abstract

  In a self-rectified x-ray generator, a tube-voltage waveform was supposed to change little bit when a tube current was varied in a wide range. We explained this phenomenon using an equivalent electric circuit of the generator, and experimentally confirmed. We also confirmed that an x-ray spectrum changed little bit with the change of a tube current. Using these facts we have established a method of time-saving spectral measurement using a germanium detector system, in which a tube current, in addition to the diameter of a detector-collimator, were adjusted.
