由大型强子对撞机（LHC）低温磁体互连接头的修复引发的为期两年的长停运1 (LS1)，为调查和校准团队提供了机会，以平滑LHC 27公里的位置，以保证其在2015年至2018年期间预期的RUN2的最佳性能。在大型强子对撞机启动后，首次测量了大型强子对撞机低温磁体的滚转角以及它们在垂直和水平（横向）上的位置。这一大规模的测量活动使许多组成部分得以重新排列，并将成为分析大型强子对撞机稳定性的重要信息来源，从而使调查小组能够预测未来运动将要发生的区域。本文概述了用于对撞机平滑、调整过程的技术和软件，并对对撞机的稳定性进行了初步分析。
The two-year Long Shut-Down 1 (LS1), triggered by the repair of the splices in the interconnections of the Large Hadron Collider (LHC) cryo-magnets, gave the opportunity to the survey and alignment team to smooth the position of the 27km of the LHC in order to guaranty its best performance for the RUN2 expected between 2015 and 2018. For the first time after the starting of the LHC, the roll angle of the LHC cryo-magnets as well as their position in vertical and in horizontal (transverse) were measured. This large measurements campaign has allowed a realignment of many components and will be an important source of information useful for the analysis of the stability of the LHC, allowing then the survey team to predict the areas where the future movements are going to take place. This paper gives an overview of the techniques and the software used for the smoothing, the realignment process and a preliminary analysis of the stability of the LHC.
