摘要
江门中微子实验（JUNO）是一个位于中国广东省地下 693 米（1800 m.w.e.）处的 2 万吨液体闪烁体低放射性多用途中微子探测器。为探测靶中产生的闪烁光，探测器配备了 17,612 个 20 英寸光电倍增管（PMT），构成大型 PMT 系统（LPMT）。此外，20 英寸 PMT 之间的间隙中还部署了 25,600 个 3 英寸光电倍增管（小型光电倍增管系统或 SPMT）。本文介绍了为 SPMT 系统开发的水下前端电子学的设计与性能。详细说明了各个电子学板及其关键组件、板间接口、系统级设计以及支持数据采集和控制的固件架构。还概述了机械与热集成、电路板验证流程以及系统性能指标。读出链路包括每个单元 128 个 PMT 通道的数字化、同步时间戳标记、电荷测量、事件打包和带宽管理。全面验证确认该系统已准备好满足 JUNO 严苛的物理目标。水下电子学的噪声水平低至 0.04 个光电子，串扰极小（低于 0.4%），带宽达 57 MB/s，确保了可靠的单光电子探测和高计数率条件下的运行。SPMT 系统现已完全集成并安装在 JUNO 中。其调试和物理性能将在未来的出版物中报告。
