Cosmogenic backgrounds to 0νββ in EXO-200
Cosmogenic backgrounds to 0νββ in EXO-200
As neutrinoless double-beta decay experiments become more sensitive and intrinsic radioactivity in detector materials is reduced, previously minor contributions to the background must be understood and eliminated. With this in mind, cosmogenic backgrounds have been studied with the EXO-200 experiment. Using the EXO-200 TPC, the muon flux (through a flat …
