Non-destructive elemental analyses have been an indispensable tool for many fields of scientific research. Prompt
-ray analysis and time of flight elemental analysis uses the energy of the
rays and the energy of neutron resonances, respectively. In both analyses, a sample is irradiated with neutrons and
rays are detected. Thus, these methods are similar and could be replaced by a single measurement. However, these methods have never been applied simultaneously before. We have first developed a novel technique which combines these methods by using an intense pulsed neutron beam. It allows us to obtain the results from both methods at the same time. Moreover, significant synergy has been achieved. Specifically, it will be used to quantify elemental concentrations in the sample that neither of these methods can be applied. Here, we demonstrate how it can be used to extract reliable information from unresolved peaks in the spectra.
