Abstract.A Cuttler-Shalev (C-S) 3 He proportional counter has been used to measure the energy spectrum of neutrons from a portable deuterium-deuterium electronic neutron generator. To improve the analysis of results from the C-S detector digital pulse shape analysis techniques have been used to eliminate neutron recoil artifacts in the recorded data. Data was collected using a 8-GHz, 10-bit waveform digitizer with its full scale corresponding to approximately 6-MeV neutrons. The measurements were made with the detector axis perpendicular to the direction of ions in the ENG in a plane 0.5-m to the side of the ENG, measuring neutrons emitted at an angle from 87.3q to 92.7q with respect to the path of ions in the ENG. The system demonstrated an energy resolution of approximately 0.040 MeV for the thermal peak and approximately 0.13 MeV at the DD neutron energy. In order to achieve the ultimate resolution capable with this type of detector it is clear that a higher-precision digitizer will be needed.

“…8 By measuring the transmission of radiation through the object as a function of position, a 2D attenuation map can be generated. 9 With a tagged 252 Cf source, both gamma and neutron radiography can be conducted simultaneously by using multiple time windows of each source-detector time correlation. 8 These radiographs can subsequently be converted to 3D tomographs by taking multiple projections through the object at different angles or by assuming cylindrical symmetry.…”
