如果未来发生银河系核心坍缩超新星爆炸，那么通过利用中微子信号迅速警告社区超新星的方向，以便启动后续光学观测，这将是至关重要的。此外，鉴于实验上限正在接近理论预测，预计对弥漫性超新星中微子背景的观测将在不久的将来产生发现。我们开发了一种新的超新星事件模拟器，用于水切伦科夫中微子探测器，如高灵敏度的Super-Kamiokande。该模拟器计算水中中微子的相互作用，用于两个模拟目的，单个核心坍缩超新星爆发和扩散超新星中微子背景。基于这个模拟器，我们可以评估确定超新星位置的精度，并估计与Super-Kamiokande中弥漫超新星中微子背景相关的事件的预期数量。在本文中，我们描述了模拟器的基本结构和它的演示。
If a Galactic core-collapse supernova explosion occurs in the future, it will be critical to rapidly alert the community to the direction of the supernova by utilizing neutrino signals in order to enable the initiation of follow-up optical observations. In addition, there is anticipation that observation of the diffuse supernova neutrino background will yield discoveries in the near future, given that experimental upper limits are approaching theoretical predictions. We have developed a new supernova event simulator for water Cherenkov neutrino detectors, such as the highly sensitive Super-Kamiokande. This simulator calculates the neutrino interaction in water for two simulation purposes, individual core-collapse supernova bursts and diffuse supernova neutrino background. Based on this simulator, we can evaluate the precision in determining the location of supernovae and estimate the expected number of events related to the diffuse supernova neutrino background in Super-Kamiokande. In this paper, we describe the basic structure of the simulator and its demonstration.
