Detector systems for imaging neutron activation analysis

This paper compares the performance of two imaging detector systems for the new technique of imaging neutron activation analysis (imaging NAA). The first system is based on secondary electron imaging, and the second employs a position sensitive charged particle detector for direct localization of beta particles. The secondary electron imaging system has demonstrated a position resolution of 20 /spl mu/m. The position sensitive beta detector has the potential for higher efficiencies with resolution being a trade off. Results presented show the feasibility of the two imaging methods for different applications of imaging NAA.<
