7 September 2017 New results from sub-3 MeV Compton spectrometer experiments

Our team at Los Alamos National Laboratory has successfully employed Compton spectrometers to measure the X-ray spectra of both continuous and flash radiographic sources. In this method, a collimated beam of X-rays incident on a converter foil ejects Compton electrons. A collimator may be inserted into the entrance of the spectrometer to narrow the angular acceptance of the forward-scattered electrons, which then enter the magnetic field region of the spectrometer. The position of the electrons at the magnet’s focal plane is proportional to the square root of their momentum, allowing the X-ray spectrum to be reconstructed. A new samarium-cobalt spectrometer with an energy range of 50 keV to 4 MeV has been fielded at two facilities. The X-ray generating machines produced intense photon beams (> 4 rad at 1 m) with spectral endpoints below 3 MeV. Recent experimental results will be presented.
