Investigation of radioactivity-induced backgrounds in EXO-200

Published

Journal Article

© 2015 American Physical Society. The search for neutrinoless double-beta decay (0νββ) requires extremely low background and a good understanding of their sources and their influence on the rate in the region of parameter space relevant to the 0νββ signal. We report on studies of various β and γ backgrounds in the liquid-xenon-based EXO-2000νββ experiment. With this work we try to better understand the location and strength of specific background sources and compare the conclusions to radioassay results taken before and during detector construction. Finally, we discuss the implications of these studies for EXO-200 as well as for the next-generation, tonne-scale nEXO detector.
