摘要
本文介绍了 Super-Kamiokande (SK) 探测器在硬件层面的标定程序与结果。特别是，我们报告了针对实验第四阶段（自 2008 年起运行新型读出电子学系统）所改进的标定方法。内容分为两部分：第一部分描述了确定解释电子学数字化输出所需常数的过程，以便获取每个光电倍增管 (PMT) 的光子计数及其到达时间等物理量；在此背景下，我们开发了一种原位程序，用于确定如 SK 等大型探测器中 PMT 的高压设置，并提出了一种在此类探测器中测量 PMT 量子效率和增益的新方法。第二部分描述了我们在蒙特卡洛模拟中对探测器的建模，特别是其水靶的光学性质及其随时间的变化，并给出了关于水质的详细研究。作为此项工作的成果，我们在宽能量范围（从几 MeV 到超过 1 TeV）内实现了满足物理分析所需的精度。例如，电荷测定精度达到 1% 水平，单光电子电荷水平下的时间分辨率为 2.1 ns，100 光电子电荷水平下为 0.5 ns。
