摘要
在nEXO中性双beta衰变探测器中（约5吨，90%136Xe，10%134Xe），对电子味 neutrino与xenon核的电荷导电相互作用进行了建模，以评估其对超新星 neutrino的灵敏度。我们采用“安格尔反应低能量产出模型”（MARLEY）事件发生器对事件率和可探测信号进行了建模。我们发现MARLEY的预测与现有理论计算在超新星 neutrino能量处的包容性截面之间存在良好一致性。由MARLEY建模的相互作用在nEXO模拟框架中进行了模拟，并通过示例重建算法来确定探测器对这些事件的重建效率。用于模拟数据的探测器响应被用于研究nEXO重建入射电子味 neutrino 能谱参数的能力，并扩展到相同同位素富集程度的更大xenon探测器。我们估计，nEXO将能够探测来自距离地球5-8千光年处的超新星的电子味 neutrino与xenon相互作用，而从观察到的相互作用中重建入射电子味 neutrino 能谱参数的能力仅限于更靠近的超新星。
