Abstract
The prompt gamma activation analysis (PGAA) facility at The University of Texas at Austin (UT) has been redesigned and reconstructed. As a result of the new shielding of the system, the neutron (at all energies) and gamma-ray backgrounds have been reduced by more than an order of magnitude, considerably improving the signal-to-noise ratio for the characteristic peaks. The prompt gamma peaks from the construction materials have also been decreased, providing better detection limits for elements. The calibration of the new system is shown in detail. All these efforts significantly improved the sensitivity and reliability of the chemical analyses performed in the facility. The characteristics of the improved PGAA system are also presented.
