论文摘要

为了满足上升高光度LHC（HL-LHC）的定时分辨率，这是一种基于低增生雪崩检测器（LGAD）（LGAD）的新检测器，高颗粒度时序检测器（HGTD）是在ATLAS的深入研究。此更新的两种类型的IHEP-NDL LGADS（BV60和BV170）是由中国科学学术学术学院（CAS）与北京北京新学术实验室（NDL）合作的高能量物理学研究所（IHEP）开发的，他们现在正在详细研究下。这些探测器在DESY的$ 5GEV $电子束上测试。选择SIPM检测器作为参考检测器，以获取LGADS的定时分辨率。 LGAD和SIPM之间的时间差的波动是通过与高斯功能拟合提取的。恒定分数判别器（CFD）方法用于缓解时间步行的效果。分别为BV60和BV170获得了$ 41 \ pm 1 ps $和$ 63 \ pm 1 ps $的定时分辨率。

To meet the timing resolution requirement of up-coming High Luminosity LHC (HL-LHC), a new detector based on the Low-Gain Avalanche Detector(LGAD), High-Granularity Timing Detector (HGTD), is under intensive research in ATLAS. Two types of IHEP-NDL LGADs(BV60 and BV170) for this update is being developed by Institute of High Energy Physics (IHEP) of Chinese Academic of Sciences (CAS) cooperated with Novel Device Laboratory (NDL) of Beijing Normal University and they are now under detailed study. These detectors are tested with $5GeV$ electron beam at DESY. A SiPM detector is chosen as a reference detector to get the timing resolution of LGADs. The fluctuation of time difference between LGAD and SiPM is extracted by fitting with a Gaussian function. Constant fraction discriminator (CFD) method is used to mitigate the effect of time walk. The timing resolution of $41 \pm 1 ps$ and $63 \pm 1 ps$ are obtained for BV60 and BV170 respectively.
