Work has been conducted at The University of Texas at Austin (UT) to analyze the detection capabilities of the prompt gamma activation analysis (PGAA) facility. The PGAA facility utilized the cold neutron beam from the UT Triga reactor. Multiple background measurements and sample blank measurements were taken so that the various sources of background could be identified and quantified. Detection limits and background interferences for a number of elements including H, B, Be, Li, and N have been determined.
