摘要
来自非常近邻超新星（如参宿四）的中微子预计将在超级神冈探测器（SK）中产生超过一千万个事件，持续10秒。在如此高的事件率下，SK模数转换板（QBEE）的缓冲区将溢出，导致对理解超新星爆发机制动力学至关重要的数据随机丢失。为解决此问题，开发了两个新的DAQ模块以辅助观测非常近邻的超新星。第一个是SN模块，设计用于仅保存超新星爆发期间击中PMT的数量；第二个是Veto模块，基于SN模块的信息对高率中微子事件进行预缩放，以防止QBEE溢出。在非常近邻超新星事件中，这些模块允许SK使用QBEE和SN模块数据从头到尾重建中微子事件率的时间演化。本文介绍了这些模块的开发和测试，以及使用闪光激光二极管生成的类超新星数据的分析。我们证明Veto模块成功防止了参宿四类超新星的DAQ溢出，并且新模块具有长期稳定性。在正常运行期间，Veto模块每月发出几次DAQ否决，导致总死时间小于1毫秒，不影响常规操作。此外，使用模拟数据我们发现，距离小于800 pc的超新星将触发Veto模块，导致观测到的中微子数据被预缩放。
