| Popis: | Work was conducted on The University of Texas at Austin Prompt Gamma Activation Analysis Facility located on Beam Port 3 of the 1.1 MW Triga reactor at the Nuclear Engineering Teaching Laboratory. This effort required that the flux weighted detector efficiency be determined. Measurements of the neutron beam intensity as a function of spatial position over the target were conducted. In addition, the point-wise detector efficiency was mapped over the area where the neutron beam hits the sample. The flux-weighted efficiency was then calculated to match the sample geometry. This average efficiency was then utilized for quantitative analysis of the prompt gamma-ray spectra. |
