良好的几何对准对于充分受益于 CMS 硅跟踪器出色的固有分辨率至关重要。由于跟踪器由大约 20000 个独立的硅传感器组成，因此需要阶次参数来进行对准。以所需的精度确定这些常数是一项极具挑战性的任务。本文提出了一种有效且计算实用的对齐算法。它适用于对由多个像素或条带模块组成的探测器结构的位置和方向进行精细校准以及各个模块的对准。通过将该算法应用于 CMS 像素检测器的对齐来研究该算法的性能。
Good geometrical alignment is essential to fully benefit from the excellent intrinsic resolution of the CMS silicon tracker. Since the tracker consists of about 20000 independent silicon sensors, of the order parameters are needed for the alignment. The determination of these constants with the required precision of about is an extremely challenging task. In this paper an effective and computationally practical alignment algorithm is presented. It is suitable for performing fine-calibration of the position and orientation of detector structures consisting of a number of pixel or strip modules as well as the alignment of individual modules. The performance of the algorithm is studied by applying it to the alignment of the CMS Pixel detector.
