Description
The Deep Underground Neutrino Experiment (DUNE) is the next generation long-baseline neutrino experiment. DUNE’s far detector modules are based on liquid argon time projection chamber (LArTPC) technology and will be the largest LArTPCs ever to be built. In this talk, I will present two topics related to DUNE that I am currently working on. The first topic is the development of an ionization laser calibration system for DUNE. This system consists of a class IV laser with steerable mirrors mounted on LAr-immersed optical periscopes to provide a well-defined source of ionization laser tracks for calibrating the DUNE detector. The primary purpose of the IoLaser system is to provide independent fine-grained measurements of detector response parameters as well as to serve as a diagnostic tool. I will introduce the IoLaser system, present the current status and discuss future plans. The second topic is related to supernovae detection in DUNE. I will present the neutrino neutral current cross sections on 40Ar at neutrino energies expected for supernova events. I will also examine the charged current cross sections using the large shell model calculations that are constrained by B(GT) and B(F) measurements but include operators to all orders in q2.
