上海光源HLS系统技术方案

地基不均匀沉降会引起加速器磁铁等关键部件的位置变化, 这些变化对加速器运行的影响越来越受到国内外各实验室的重视. 在建的上海三代同步辐射光源地处地质条件复杂的上海浦东, 有必要建立对加速器所在的地基和关键部件的不均匀沉降的监测系统. 静力水准系统(Hydrostatic Levelling System, HLS)主要用于实时监测地基以及支撑在垂直方向(高程)的位置变化. 本文讨论了上海光源中静力水准系统的设计方案, 主要参数, 以及理论计算等. 通过讨论可以更全面了解在加速器中建立静力水准系统的重要性和必要性.

Technological Plan of HLS in SSRF

The place change of the key inserts,different kinds of magnets for instance,in an accelerator caused by the uneven earth subside will affect the accelerator commission.All accelerator laboratories,at home and abroad have taken the influences more and more seriously.The Shanghai Synchrotron Radiation Facility(SSRF)under construction is located at Pudong,Shanhai,where geological condition is complicated.It is necessary to establish a monitoring system to monitor the uneven subside of foundation and key parts of the accelerator.The Hydrostatic Leveling System (HLS)is used to real time monitor the vertical displacement of the foundation and the supports of the key inserts in accelerator.This paper discusses the HLS's design plan,the principal parameters and the theoretical calculation.By discussion we can comprehend the importance and necessity to establish HLS in an accelerator in an all-round way.
