微型助推器中微子实验（MicroBooNE）是费米实验室的液态氩时间投影室（LArTPC）中微子探测器，自2015年以来一直在运行。它的目标是进行v-Ar横截面测量，探索MiniBooNE实验报告的低能过剩，并进行对惰性中微子振荡的联合搜索，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。由于MicroBooNE目前处于研发阶段，它为实现和测试基于tpc的触发器提供了一个独特的机会，作为对深地下中微子实验（DUNE）的研发。本研究旨在解决的DUNE技术挑战之一是利用TPC信号信息有效地自触发LArTPC。这种能力将使人们能够在DUNE中搜索罕见的过程，比如来自潜在星系超新星爆发的中微子相互作用。本次演讲将介绍MicroBooNE TPC读出系统和正在进行的研发工作，以开发和演示基于TPC的触发。
The Micro Booster Neutrino Experiment (MicroBooNE) is a Liquid Argon Time Projection Chamber (LArTPC) neutrino detector at Fermilab that has been operating since 2015. It aims to perform v-Ar cross-section measurements, explore the low-energy excess reported by the MiniBooNE experiment and perform a combined search for sterile neutrino oscillations as part of three LArTPCs that make up the Short Baseline Neutrino (SBN) Program at Fermilab. Since MicroBooNE is currently in an R&D phase, it offers a unique opportunity for the implementation and testing of TPC-based triggers as R&D towards the Deep Underground Neutrino Experiment (DUNE). One of the technical challenges of DUNE that we aim to address with this study is that of efficient self-triggering of a LArTPC utilizing TPC signal information. This capability will enable searches for rare processes in DUNE, such as neutrino interactions from a potential galactic supernova burst. This talk will describe the MicroBooNE TPC readout system and ongoing R&D efforts to develop and demonstrate TPC-based triggering.
