Abstract
The Deep Underground Neutrino Experiment (DUNE), the U.S. flagship neutrino experiment, relies on high purity liquid argon (LAr) for optimal detector performance. Ensuring and monitoring LAr purity is crucial, as electronegative impurities can degrade signal quality in detectors. As part of Proto-DUNE, a prototype detector at CERN for DUNE, this study explores the use of Bismuth-207 (Bi-207) as a novel tool for real-time LAr purity monitoring and calibration. Bi-207 emits monochromatic internal conversion electrons, allowing precise impurity assessment without interfering with standard detector operations. By simulating the behavior of radioactive Bi-207 and analyzing data from the Proto-DUNE Vertical Drift detector, this research evaluates the gain factor, a critical parameter influencing charge signal attenuation and measurement precision. The goal of this research is to refine the Bi-207 based purity monitoring system, enhancing impurity detection techniques for future LArTPC experiments, including DUNE. These improvements will contribute to the long-term stability and performance of next-generation neutrino detectors.
