Photo-induced Charge and Light Calibration for nEXO

The 5-ton liquid xenon TPC of the nEXO experiment will search for the elusive neutrinoless double beta decay of ¹³⁶Xe with a half-life sensitivity goal of > 10²⁸ years. Calibrations for the nEXO TPC will provide the capability to measure beta, gamma and alpha deposits over the full range of energies and achieve this sensitivity goal. This presentation will describe some of the calibration strategies and plans for the nEXO TPC. Including the status of R&D at UMass Amherst on novel calibration strategies of electron drift properties using a dual grid ionization chamber for ionization charge clusters and photon detection calibration.
