A differential absorption spectrometer for determining flash X-ray spectra from 10 to 2000 keV

A differential absorption spectrometer was developed and used on various bremsstrahlung sources (Pelletron, Saturn, and SPEED), with endpoint energies from 150 to 2000 keV. Spectral data were unfolded using response functions generated by TIGER and CEPXS/ONETRAN. Unfolded spectra are qualitatively in agreement with predicted spectra for steady-state bremsstrahlung sources from 150 DeV and 900 keV. Applications and limitations of the diagnostic are discussed, and modifications and simplifications are suggested.<
