The Design, Development and Testing of an Automated System for Fast Neutron Activation Analysis

摘要

An automated system was designed, built, and tested which is capable of the analysis of materials by activation with 14 Mev neutrons. The system uses a 150 Kev Cock-croft Walton accelerator for the production of neutrons, a pneumatic system for the rapid transfer of samples, and a sodium iodide scintillation detector for counting samples. The system was tested by performing activation analyses of aluminum and concrete samples, and a computer program was written which theoretically predicts the spectrum which would result from the activation analyses of any material.
