Abstract
The observation of neutrinoless double beta decay would confirm the Majorana nature of neutrinos. nEXO is a proposed single-phase time projection chamber with 5 tons of liquid xenon (enriched ∼ ∼ 90% % in 136 ¹³⁶ Xe) to search for neutrinoless double beta decay of 136 ¹³⁶ Xe. At the top of a cylindrical TPC, charge is collected by silica “tiles” patterned with crossed metallic strips. The VUV-sensitive silicon photo-multipliers installed all along the barrel of TPC facilitate the photon detection. The R & D efforts on charge collection and photon detection toward achieving 1% % energy resolution (σE) ((σ/E)) at Q-value along with signal and background discrimination that would help toward reaching target half-life sensitivity of ∼ ∼ 1028 ²⁸ years will be discussed.
