论文摘要
提出了针对LHCB Velo升级开发的传感器原型的空间分辨率和检测效率的全面研究。使用质子和乳头的强子混合物在CERN SPS H8束系上收集数据样品，其力量约为180 GEV/c。使用辐照和非辐照传感器表征传感器性能。辐照样品的最大通量为$ \ mathrm {8 \ times10^{15} 〜1〜Mev〜n_ {eq} 〜cm^{ - 2}}} $，均为质子和中子。测量空间分辨率，将检测到的命中与TimePix3望远镜重建的轨道预测的位置进行比较。该分辨率用于不同的应用偏置电压和轨道角度，传感器厚度和植入物尺寸。
A comprehensive study of the spatial resolution and detection efficiency of sensor prototypes developed for the LHCb VELO upgrade is presented. Data samples were collected at the CERN SPS H8 beam line using a hadron mixture of protons and pions with momenta of approximately 180 GeV/c. The sensor performance was characterised using both irradiated and non-irradiated sensors. Irradiated samples were subjected to a maximum fluence of $\mathrm{8\times10^{15}~1~MeV~n_{eq}~cm^{-2}}$, of both protons and neutrons. The spatial resolution is measured comparing the detected hits to the position as predicted by tracks reconstructed by the Timepix3 telescope. The resolution is presented for different applied bias voltages and track angles, sensor thickness and implant size.
