Description
The nEXO detector features a 5 tonne time projection chamber filled with liquid xenon (LXe) enriched to 90% in the A=136 isotope. nEXO aims to detect 136Xe neutrinoless double beta decay (0𝜈ββ) with a 90% CL sensitivity >10$^{28}$ years, using vacuum ultraviolet (VUV) silicon photomultipliers (SiPMs) as scintillation sensors. This poster will focus on the current and future plans for studying SiPM devices being considered for nEXO under different conditions. These include operational stability in LXe, the influence of external electric fields and the effects of charge accumulation on the surface from a calibration source. In addition we also discuss the plans for integration and testing of large area SiPMs and tile modules, as part of the detector integration strategy adopted by nEXO.
