Abstract:

 

``Low-energy’’ (~10 MeV) neutrinos are a stellar portal, allowing us to peak inside the Sun and core-collapse supernovae. This thesis examines the low-energy response and calibration of LArTPC (Liquid Argon Time Projection Chamber) prototypes for a future neutrino observatory, DUNE. The discussion will focus both on calorimetry (the measurement of a delta-ray spectrum) and the correction of anticipated detector defects (warped electric fields). Additionally, I will discuss DUNE’s sensitivity to exotic ~200 MeV neutrinos from the Sun which could be beacons of dark matter.
