摘要
为满足即将到来的高亮度LHC（HL-LHC）对时间分辨率的要求，ATLAS实验正深入研究一种基于低增益雪崩探测器（LGAD）的新探测器——高粒度时间探测器（HGTD）。中国科学院高能物理研究所（IHEP）与北京师范大学新型器件实验室（NDL）合作，正在开发用于此升级的两种IHEP-NDL LGAD（BV60和BV170），目前正进行详细研究。这些探测器在DESY的 电子束下进行了测试。选用SiPM探测器作为参考探测器以获取LGAD的时间分辨率。LGAD与SiPM间时间差的涨落通过高斯函数拟合提取。采用恒比甄别器（CFD）方法以减轻时间游走效应。BV60和BV170的时间分辨率分别获得为 和 。
