Abstract

The Short Baseline Near Detector (SBND) is a 112 ton active mass liquid argon time projection chamber (LArTPC) that will begin operations in the Booster Neutrino Beamline at Fermilab in 2020. Its main physics goals include high-statistics measurements of neutrino-argon interaction cross-sections and searches for sterile neutrino oscillations as part of three LArTPCs that make up the Short Baseline Neutrino (SBN) Program at Fermilab. In addition, SBND serves as an R\&D platform for future LArTPC detectors such as those employed by the Deep Underground Neutrino Experiment (DUNE). One of the technical challenges of DUNE that SBND aims to address is that of efficient self-triggering utilizing TPC signal information. Such capability will enable searches for rare processes in the DUNE far detector, for example neutrino interactions from a potential galactic supernova burst, or proton decay. These proceedings describe the SBND TPC readout system and ongoing R\&D efforts to develop and demonstrate efficient TPC-based self-triggering.
