论文摘要
Nova长基线中微子实验使用一对大型,分段的液体阶段器热量表来研究中微子振荡,使用Fermilab Numi Beam的GEV尺度中微子。这些探测器也对中微子的通量敏感,这些中微子在核心折叠超新星期间通过碳碳的反向衰减相互作用在碳氧化的能量上以$ \ Mathcal {o}(10〜 \ text {mev})$。该签名提供了一种研究在我们银河系中发生的核心偏离超新星的主要能量释放模式的方法。我们描述了NOVA实验开发和采用的数据驱动软件触发系统,以识别和记录附近银河系超新星的中微子数据。 This technique has been used by NOvA to self-trigger on potential core-collapse supernovae in our galaxy, with an estimated sensitivity reaching out to 10~kpc distance while achieving a detection efficiency of 23\% to 49\% for supernovae from progenitor stars with masses of 9.6M$_\odot$ to 27M$_\odot$, respectively.
The NOvA long-baseline neutrino experiment uses a pair of large, segmented, liquid-scintillator calorimeters to study neutrino oscillations, using GeV-scale neutrinos from the Fermilab NuMI beam. These detectors are also sensitive to the flux of neutrinos which are emitted during a core-collapse supernova through inverse beta decay interactions on carbon at energies of $\mathcal{O}(10~\text{MeV})$. This signature provides a means to study the dominant mode of energy release for a core-collapse supernova occurring in our galaxy. We describe the data-driven software trigger system developed and employed by the NOvA experiment to identify and record neutrino data from nearby galactic supernovae. This technique has been used by NOvA to self-trigger on potential core-collapse supernovae in our galaxy, with an estimated sensitivity reaching out to 10~kpc distance while achieving a detection efficiency of 23\% to 49\% for supernovae from progenitor stars with masses of 9.6M$_\odot$ to 27M$_\odot$, respectively.
