摘要

The Solution Assay Instrument is an in-line quantification system for measurements of high concentration solutions in gloveboxes. Elevated environmental background levels significantly hinder the ability to detect low concentration solutions. The effectiveness of adding Compton suppression to reduce detection limits was determined with MCNP (Monte Carlo N-Particle). Modification of the source and glovebox geometry were performed to optimize the detection limit. The reduction of the continuum with Compton suppression for the optimized setup was 34.6% at 129 keV. With geometry modifications adding Compton suppression and increasing count rate, a resulting 14.14% reduced detection limit was produced.
