Broadening the dynamic range of PGAA using high-efficiency detector array
We want to study the improvement we can achieve in the analytical sensitivity of prompt gamma activation analysis using the most advanced gamma-spectrometry system. The high counting efficiency and the coincidence possibility with multiple HPGe detectors offers a unique opportunity to unfold the spectra where a strong matrix masks the weak signal from trace components, like Cl a highly important corrosive in Fe or silicate matrices. The detection limits and the dynamic range for such measurements have already been determined at FRM II, Garching in high-flux cold neutron beam with a single Compton-suppressed HPGe detector and were found to be about 80 ppm for the iron matrix. More than one order of magnitude improvement is expected. Small-mass model samples will be used with known amount of trace Cl on the 1-100 ppm level using Fe (and Si) plates/wafer together with PVC films. The results will help us to conclude about the development strategies in nuclear analytics.
