Observation of radon mitigation in MicroBooNE by a liquid argon filtration system

The MicroBooNE liquid argon time projection chamber maintains a high degree of liquid argon purity by the use of a filter system that removes electronegative particles from continuously circulated water, restarted boil off, and externally supplied argon gas. This is the first report of radon mitigation in liquid argon with a large-scale copper-based filter, and it could be a radon mitigation strategy for future large LArTPCs.
