欧洲LEP离子对撞机的稳定性分析

Stability Analysis of European LEP Particle Collider

介绍加速器的整体稳定性分析的过程和方法，就是利用每年一度的加速器的水准测量所得的垂直偏差来分析加速器和隧道的稳定性。整个分析过程分为四个阶段：１）数据的筛选和恢复；２）建立一种不受数据处理基准和其它不确定因素影响的且能精确反映加速器变形的技术；３）建立一种能区分加速器变形和隧道变形的技术；４）对其变形进行分析和描述。

In this article, the overall stability of the acelerator is checked based on the vertical offsets. The deformation and the movement of the elements are analyzed in four stages.1) The data, datafiltering and data-restoring;2) the technique which would precisely reflect the deformation of the accelerator without any influence of the adjustment datum or other uncertainty parameters;3) distinction of the deformation of the tunnel from the movement of the elements;4) description of this deformation.
