Progress and prospect of engineering control network for particle accelerator

随着高能物理研究对粒子碰撞能量需求的不断增大,粒子加速器的规模愈加宏大,对工程控制网的设计、测量和维持提出了极大的挑战。为此,本文在归纳整理国内外研究现状的基础上,围绕加速器控制网结构及精度要求、几何参考框架选取、测量仪器与标志、网形与观测方案、观测值归算与平差等问题,凝练了大型粒子加速器精密控制网的关键技术,最后给出了巨型加速器工程高精度三维控制网建立技术的研究建议。

As the increasing demand of particle collision energy in high energy physical research,the size of the particle accelerator is increasing,which puts forward a challenge to the design,measuring and maintenance of engineering control network.For this purpose,on the basis of summarizing and sorting out the research status at home and abroad,this paper refines the key technologies of structure and accuracy requirement,the selection of geometric reference framework,measuring instruments and markers,net form of control network and observation scheme,and the reduction and adjustment of observed value for giant particle accelerator control network.At last,some technical prospects and research ideas of the high precision three-dimensional control network construction technology are put forward for giant accelerator engineering.
