Abstract

Signal loss is the main limitation on tracking/vertexing performance due to radiation damage effect to hybrid pixel detectors when irradiated at fluences expected at High Luminosity LHC (HL-LHC). It is important to have reliable predictions on the charge collection performance after irradiation in order to predict operational voltage values and test tracking algorithms robustness. In this paper the validation of combined TCAD and Monte Carlo simulations of hybrid silicon planar pixels sensors will be presented. In particular different trapping models will be compared to identify the one giving the best predictions. Eventually predictions on the collected charge performance of planar pixels modules at HL-LHC will be discussed.

辐照混合平面像素模组在HL-LHC预期影响下的模拟

在高亮度大型强子对撞机（HL-LHC）中，混合像素探测器受到辐射损伤，导致信号丢失，是影响跟踪/顶点化性能的主要因素。对辐照后的电荷收集性能进行可靠的预测是预测工作电压值和测试跟踪算法鲁棒性的重要手段。本文将对混合硅平面像素传感器的TCAD和蒙特卡罗模拟相结合的验证进行介绍。特别是，将比较不同的捕获模型，以确定给出最佳预测的模型。最后讨论了平面像素模块在HL-LHC上电荷收集性能的预测。

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.
