DESCRIPTION:Speakers: Jonathan Haefner (Harvard University)\nThe NEXT expe
 riment is a neutrino physics program searching for neutrinoless double bet
 a decay using high pressure gaseous xenon time projection chambers (HPGXeT
 PC). The HPGXeTPC technology offers several advantages\, including excelle
 nt energy resolution\, topological event discrimination\, and calibration 
 with gaseous\, radioactive krypton. We will discuss the power of this cali
 bration technique for characterizing the electroluminescence region\, wher
 e S2 signals are produced. We discuss the impact of variation in the volta
 ge on light production and event detection\, as well as demonstrating capa
 bility to extract structural information about the EL gap from Kr calibrat
 ion data. We will furthermore show an improved understanding of diffusion 
 related effects in our detector.\n\nhttps://indico.physics.ucsd.edu/event/
