摘要

ATLAS和CMS实验的高亮度升级包括专用子探测器来执行最小电离粒子(MIPs)的时间戳。这些探测器将暴露在1.5-2.5 × 10 15 n eq / cm2的影响范围内，在其寿命结束时，低增益雪崩二极管(LGAD)已被选择作为其基线检测技术。为了更好地了解LGAD探测器在这些环境中的性能，进行了中子和质子辐照后增益层退化的研究，辐照的影响可达1.5 × 10 15 n eq / cm2。本研究选择了滨松光子(HPK)和国家中心Microelectrónica (CNM-IMB)制造的LGADs，并比较了在卢比雅那Jožef Stefan研究所(JSI)的反应堆中子和在CERN-PS的24 GeV/c质子照射后的增益层退化情况。

Gain layer degradation study after neutron and proton irradiations in Low Gain Avalanche Diodes

Abstract The high-luminosity upgrade of the ATLAS and CMS experiments includes dedicated sub-detectors to perform the time-stamping of minimum ionizing particles (MIPs). These detectors will be exposed up to fluences in the range of 1.5-2.5 × 10 15 n eq /cm 2 at the end of their lifetime and, Low Gain Avalanche Diode (LGAD) has been chosen as their baseline detection technology. To better understand the performance of LGAD detectors in these environments, a gain layer degradation study after neutron and proton irradiations up to a fluence of 1.5 × 10 15 n eq /cm 2 was performed. LGADs manufactured at Hamamatsu Photonics (HPK) and Centro Nacional de Microelectrónica (CNM-IMB) were chosen for this study and, a comparison in the gain layer degradation after exposure to reactor neutrons at the Jožef Stefan Institute (JSI) in Ljubjana and 24 GeV/c protons at the CERN-PS is presented here.
