DESCRIPTION:Speakers: Clarke Hardy (Stanford University)\nThe nEXO experim
 ent is a planned ton-scale liquid xenon time projection chamber (TPC) desi
 gned to search for neutrinoless double beta decay (0vBB) with a half-life 
 sensitivity beyond 10$^{28}$ years. Optimal energy resolution in nEXO requ
 ires the precise reconstruction of the scintillation light signal\, correc
 ted by the position- and time-dependent light collection efficiency (or 
 “lightmap”) throughout the active volume. An injected xenon 127 source
  is being considered for the lightmap reconstruction as it allows for in-s
 itu calibrations of the light response\, particularly in the center of the
  TPC where the use of external sources is limited by the attenuation of ga
 mmas in the liquid xenon. Multiple potential techniques for lightmap recon
 struction are being explored\, including a neural net and a kernel smoothi
 ng algorithm. This talk will present projections of the lightmap reconstru
 ction capability from simulated xenon 127 decays and a discussion of the t
 echniques involved.\n\nhttps://indico.physics.ucsd.edu/event/1/contributio
