高精度时钟分发与同步在大型物理实验中是必不可少的组成部分，它是精密时间测量以及多模块协同工作的前提。在国家自然科学基金委重大科研仪器研制专项——低温高密核物质探测谱仪（CEE）的研制中，时间测量要求达到最高约为10 ps的精度，这相较于目前稳定运行的大型物理实验中约20 ps的精度有明显提高，因此也就对时钟分发精度提出了极高的要求。本报告中将介绍基于级联架构的时钟分发系统以实现长距离、多节点、高精度的时钟分发与同步。此外，针对新一代加速器装置中特殊频点时钟分发以及自动相位补偿的挑战，本报告将介绍在兼容标准频点时钟分发的基础上，基于Whiter Rabbit (WR)结合Direct Digital Frequency Synthesis (DDS)方案实现高精度、长距离、特殊频率时钟信号分发并进行自动相位补偿的时钟系统设计。

海铃计划（the TRIDENT experiment）是目前筹建于中国南海海域的新一代深海中微子望远镜实验，其主要科学目标是通过探测高能天体中微子来研究宇宙射线起源等重要物理问题。对于深海中微子望远镜而言，其所在的海水介质对于切伦科夫光子的散射和吸收效应将会直接影响探测阵列的方向指向能力以及能量阈值。此外，动态的海水介质也会导致其光学性质因时变化。本次报告将会介绍一种适用于未来海铃计划的基于CMOS相机的新型刻度系统，以实现对于深海海水的光学性质的实时、精确测量。为了实现初步的技术论证，2021年9月，“海铃探路者”（The TRIDENT Pathfinder）实验搭载该系统，于南海西沙群岛附近3500m深海进行了首次实地测试，并最终成功解码了包括衰减长度，吸收长度等重要光学性质。

其探测单元基本组成为：天线、低噪声放大器、Wifi、太阳能供电装置、DAQ板，DAQ板的作用在于对天线的输出信号进行电子学处理，同时对电源状态、温度、压强等诸多变量进行监测，将采集的数据通过Wifi传输至中心站，因此DAQ板对宇宙线信号的探测起着举足轻重的作用，为了保证探测的精度与效率，需要对DAQ板的基本功能与性能进行测试，其中，功能测试包括：信号采集与传输、FPGA触发算法、FPGA滤波算法等，性能测试包括：ADC性能、系统增益与相位、GPS时间性能等。
本次展示内容主要为对DAQ板的测试结果以及对DAQ板进一步改进完善的意见。

中国散裂中子源（CSNS）规划的大部分中子谱仪都是基于3He管位置灵敏探测器。为了减少空气对中子散射实验的影响，探测器需要放置在真空腔中，同时为了减少穿越真空腔的电缆数量以及提高电信号的信噪比，电子学读出系统也需要紧靠探测器放置于真空腔中。由于3He管探测器的命中位置是通过电荷分配法计算得到的，准确的脉冲峰值获取需要ADC工作在高速采集状态下，目前基于这种方法的读出电子学系统功耗都较高，不适合应用在没有空气对流，电子学散热困难的真空中。因此,为实现电子学在高速高精度采样的同时还能以极低功耗运行的目标，我们从以下几个方面进行了研究：（1）用低功耗 ASIC 芯片代替分立器件模拟前端电路； (2) 使用先进低功耗ADC芯片和FPGA； (3) 通过时钟门控系统以降低数字动态功耗；...
