MAJORANA Demonstrator (MJD, DOE, Neutrinoless Double Beta Decay Expt.) Designed experiment to test emanation from tools being used inside of glove box environment to account for radon backgroundRan through daily checklist and fixed any irregularities in underground lab spaceMaintained appropriate acidic, copper nugget, and conductivity levels for the growth of ultra-pure copper

Without a purged radon barrier, the background from radon daughters would be the largest background source for the experiment. The radon barrier consists of metal shielding and gasket materials. This made it important to study the radon diffusion properties of gasket materials.-Built an apparatus to measure diffusion of radon through various gaskets -Analyzed time series data to determine diffusion properties of gaskets-Presented gasket data at a SuperCDMS collaboration meeting and APS conference Calculated diffusion properties of various materials using results from LUX-ZEPLIN databaseRedesigned a filter box to filter out signals for a radon emanation setup. Previous filter box was suspect of damaging emanation detector by creating voltage spikes greater than detector diode rating
