MAX IV Laboratory is the Swedish national particle accelerator that currently provides the world’s most brilliant X-rays for research. MAX IV Laboratory has two storage rings as well as a 300-meter linear accelerator with hundreds of components not only to be relatively aligned with tight tolerances but also to be absolutely aligned with respect to the global coordinate system of the facility. An advanced particle accelerator of this kind requires high-precision alignment of all its sensitive components through a multiple-stage process. We recognized the need for a full realignment of the linear accelerator due to the beam-based measurements done by our accelerator scientists as well as the expected alignment deflections since its initial alignment in 2015. Partial realignment of an operational facility – in this case, the realignment of the entire linear accelerator – involves serious risks, as it must precisely maintain its consistency with the storage rings and the beamlines of the facility that are already aligned and operational. This paper serves as a guide for large-scale realignment problems that involve surveying, outlier analysis, fiducialization, boundary conditions, solution/optimization of reference-networks, and physical realignment of the components. This work took place over 2 years, where the entire realignment process was successfully carried out and finally verified.

MAX IV实验室是瑞典的国家粒子加速器，目前提供世界上最绚丽的X射线用于研究。MAX IV实验室具有两个存储环以及一个300米的线性加速器，该加速器具有数百个组件，这些组件不仅要以严格的公差相对对准，而且要相对于设施的全局坐标系绝对对准。这种先进的粒子加速器需要通过多阶段过程对其所有敏感组件进行高精度对准。我们认识到，由于加速器科学家进行的基于波束的测量以及自2015年首次对准以来的预期对准偏差，需要对线性加速器进行完全重新对准。运营设施的部分重新对准–在这种情况下，整个直线加速器的重新对准会带来严重的风险，因为它必须精确地保持与已对准且可运行的设施的存储环和射线束的一致性。本文可作为大规模重排问题的指南，这些问题涉及调查，异常值分析，基准化，边界条件，参考网络的求解/优化以及组件的物理重排。这项工作进行了2年，在此期间，整个调整过程都得到了成功执行，并最终得到了验证。离群分析，基准化，边界条件，参考网络的求解/优化以及组件的物理重新对齐。这项工作进行了2年，在此期间，整个调整过程都得到了成功执行，并最终得到了验证。离群分析，基准化，边界条件，参考网络的求解/优化以及组件的物理重新对齐。这项工作进行了2年，在此期间，整个调整过程都得到了成功执行，并最终得到了验证。
