论文摘要

我们报告了Hamamatsu（HPK）在Atlas中使用Hamamatsu（HPK）作为高颗粒度时正时探测器（HGTD）的原型中的中子和低增益雪崩探测器（LGAD）的辐射运动结果。有效厚度为50〜 $μm的传感器以大约2 $ \ times $的步骤辐照，达到$ 3 \ times10^{15}〜\ mathrm {n_ {eq} cm^{ - 2}}} $。随着通量的函数，将报告以$ -30^{\ Circ} $的方式报告收集的辐照传感器的收取费用和时间分辨率。

We report on the results of a radiation campaign with neutrons and protons of Low Gain Avalanche Detectors (LGAD) produced by Hamamatsu (HPK) as prototypes for the High-Granularity Timing Detector (HGTD) in ATLAS. Sensors with an active thickness of 50~$μ$m were irradiated in steps of roughly 2$\times$ up to a fluence of $3\times10^{15}~\mathrm{n_{eq}cm^{-2}}$. As a function of the fluence, the collected charge and time resolution of the irradiated sensors will be reported for operation at $-30^{\circ}$.
