摘要：
若未来发生银河系超新星爆炸，利用中微子信号快速向学界通报超新星方向以启动后续光学观测将至关重要。此外，鉴于实验上限正逼近理论预测，人们预期近期将通过弥散超新星中微子背景观测取得新发现。我们为水切伦科夫中微子探测器（如高灵敏度的Super-Kamiokande（超级神冈探测器））开发了一款新型超新星事件模拟器。该模拟器针对上述两类超新星中微子计算其在水中的相互作用，旨在评估超新星定位精度，并估算Super-Kamiokande中弥散超新星中微子背景的预期事例数。本文阐述了该模拟器的基本结构及其演示验证情况。
英文摘要：
If a galactic 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 the two types of supernova neutrinos described above. Its purpose is to evaluate the precision in determining the location of supernovae and to 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.
