Description
The EXO-200 detector, a 175 kg single phase liquid xenon time projection chamber, is the most sensitive experiment in the Xe-136 neutrino-less double beta decay search. Its success bodes well for the future multi-ton scale next phase, nEXO. The abilities to achieve energy resolution of σ/E = 1.53% at the Q-value of 2458 keV and reduce α and γ-ray backgrounds make it feasible to improve sensitivity via scaling up in mass. EXO-200 also demonstrates technological achievements such as in situ xenon purification and the construction of a TPC from only low background materials, while experiencing challenges such as high voltage breakdown in liquid xenon. We describe the EXO-200 detector performance over three years of running and highlight the lessons applied to nEXO design.
