摘要“ATLAS ITk条传感器协作”研发小组开发了第二代单侧n+-in-p型微带传感器，用于高亮度（HL）LHC的ATLAS实验的跟踪器升级。全尺寸传感器的尺寸约为97× 97 mm 2，设计公差为1.1× 1015 neq/cm 2，预计在HL-LHC的通量。每个传感器有4列1280个单独的23.9 mm长的通道，以74.5 μ m的间距排列。评估了由Hamamatsu Photonics生产的包括120个传感器的四个批次的机械、电体积和条带特性。进行光学显微镜测量以获得传感器表面轮廓。测量每个单独传感器的漏电流和体电容特性。对于跨传感器批次的样品条，测量条间电容和电阻以及穿通保护结构的特性。使用多通道探针卡测量三批100个传感器的每个单独通道的漏电流、耦合电容和偏置电阻。本文介绍了120个未辐照传感器的汇编结果，包括近500，000个探测条带的总结结果。的各种参数和频率依赖性的测试电容的反向偏置电压的依赖性的结果被包括用于验证所使用的实验方法。将结果与指定值进行比较，几乎所有传感器都符合规格。
Abstract The “ATLAS ITk Strip Sensor Collaboration” R&D group has developed a second iteration of single-sided n+-in-p type micro-strip sensors for use in the tracker upgrade of the ATLAS experiment at the High-Luminosity (HL) LHC. The full size sensors measure approximately 97× 97 mm 2 and are designed for tolerance against the 1.1× 10 15 n eq/cm 2 fluence expected at the HL-LHC. Each sensor has 4 columns of 1280 individual 23.9 mm long channels, arranged at 74.5 μ m pitch. Four batches comprising 120 sensors produced by Hamamatsu Photonics were evaluated for their mechanical, and electrical bulk and strip characteristics. Optical microscopy measurements were performed to obtain the sensor surface profile. Leakage current and bulk capacitance properties were measured for each individual sensor. For sample strips across the sensor batches, the inter-strip capacitance and resistance as well as properties of the punch-through protection structure were measured. A multi-channel probecard was used to measure leakage current, coupling capacitance and bias resistance for each individual channel of 100 sensors in three batches. The compiled results for 120 unirradiated sensors are presented in this paper, including summary results for almost 500,000 strips probed. Results on the reverse bias voltage dependence of various parameters and frequency dependence of tested capacitances are included for validation of the experimental methods used. Comparing results with specified values, almost all sensors fall well within specification.
