Abstract

Characterization of strip and pixel AC-LGAD devices with both laser TCT and probe station (IV/CV) will be shown on AC-LGADs irradiated with 1 MeV reactor neutrons at JSI/Ljubljana and with 400 MeV protons at FNAL ITA to fluences from 1e13

n_{e q} / {cm}^{2}

to a few times 1e15

n_{e q} / {cm}^{2}

. This study was conducted within the scope of the ePIC detector time of flight (TOF) layer R&D program at the EIC, which will feature AC-LGADs with strip and pixel geometry. Sensors in the TOF layer will receive up to 1e13

n_{e q} / {cm}^{2}

fluence over the lifetime of the experiment.

中子和质子辐照AC-LGAD传感器的性能

在JSI/卢布尔雅那用1 MeV反应堆中子照射AC-LGAD，在FNAL ITA用400 MeV质子照射AC-LGAD，影响从1e13 neq/cm2到几倍于1e15 neq/cm2，用激光TCT和探针站（IV/CV）对条形和像素形AC-LGAD器件进行表征。这项研究是在EIC的ePIC探测器飞行时间（TOF）层研发计划的范围内进行的，该计划将采用具有条形和像素几何形状的ac - lgad。在实验的整个生命周期中，TOF层中的传感器将接收到高达1e13 neq/cm2的影响。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
