Optimization of Gamma Spectroscopy Setup for Am-Be based PGNAA Setup
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 12
Abstract
Gamma Spectroscopy setup is an integral part of prompt gamma activation setup. Gamma spectroscopy setup consists of a Canberra Coaxial HpGe semiconductor detector and a Canberra digital spectrum analyzer (DSA1000).The detector calibration measurement were carried out for energy range 59.5 keV to 4439.4 keV with standard gamma sources, natural background (40K and 208Tl) gammas and ambient gamma from of 241Am4Be neutron source. Full energy peak efficiency is estimated for the energy range 59.5 keV to 1332.49 keV. Important detector performance parameter like full width at half maximum (FWHM), full width at one tenth of maximum (FWTM), peak-to-Compton ratio and gain variation of conversion factor with amplifier gain were also estimated. Optimization of digital signal processing (DSP) parameters for digital MCA were also carried out.
