“A linear Paul trap for barium tagging of neutrinoless double beta decay in nEXO”

Departmental Doctoral Oral Examination

Abstract:
nEXO is the next-generation Enriched Xenon Observatory searching for neutrinoless double beta decay (0νββ) in ¹³⁶Xe. If observed, 0νββ will validate neutrino to be its own anti-particle and determine the absolute mass scale of the neutrinos. nEXO's sensitivity is limited by the background level. Barium tagging is the ultimate background rejection method using the coincidence detection of  ¹³⁶Ba as the daughter nucleus.
