短基线近探测器(SBND)是一个112吨重的主动质量液态Ar时间投影室(LArTPC)，将于2020年开始在费米实验室的助推器中微子光束线上运行。它的主要物理目标包括对中微子-Ar相互作用截面的高统计测量，以及搜索不育中微子振荡，作为组成费米实验室短基线中微子(SBN)计划的三个LArTPC的一部分。此外，SBND是未来LArTPC探测器的研发平台，如深地中微子实验(DUNE)所使用的探测器。SBND致力于解决的沙丘的技术挑战之一是利用TPC信号信息有效地自触发。这种能力将使在沙丘远处探测器中搜索罕见的过程成为可能，例如来自潜在银河系超新星爆发的中微子相互作用，或质子衰变。这些会议记录描述了SBND TPC读出系统和正在进行的研发工作，以开发和展示高效的基于TPC的自触发。
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.
