Sensor Simulation and position calibration for the CMS pixel detector

V. Chiochia, E. Alagoz, M. Swartz

摘要:

在本文中,详细的模拟辐照像素传感器被用来研究辐射损伤的电荷共享和位置确定的影响。模拟实现了一个模型的辐射损伤,包括两个缺陷的水平与相反的电荷状态和捕获的载流子。我们表明,从模拟中提取的电荷共享函数可以参数化为像素间位置的函数,并用于提高位置确定。对于辐照到Φ =5.9x10^14 n/cm^2的传感器,校准后可以实现低于15 um的位置分辨率。

英文摘要:

In this paper a detailed simulation of irradiated pixel sensors was used to investigate the effects of radiation damage on charge sharing and position determination. The simulation implements a model of radiation damage by including two defect levels with opposite charge states and trapping of charge carriers. We show that charge sharing functions extracted from the simulation can be parameterized as a function of the inter-pixel position and used to improve the position determination. For sensors irradiated to Phi=5.9x10^14 n/cm^2 a position resolution below 15 um can be achieved after calibration.
