Description
Beam orbit stability is the key indicator for current synchrotron light sources,which has a direct effect upon accelerator performance as well as quality and stability of synchrotron light in experimental stations.This paper aims to realize the nano-scale stability requirement of the BPM independent support in limited narrow space for HALF.By establishing a theorical model and simulation analysis,an optimal operating environment with suppressed interference factors can be created for the BPM.The process and technology of controlling local foundation micro-vibration,as well as analysis of vibration stability and study on the vibration isolation and damping technology of the system under the environment of complicated excitations are carried out.Furthermore,the analysis of thermal stability and study on the heat preservation and insulation technology of the system under the environment of multi-physical fields are conducted.Based on the requirements,we have developed a prototype with the eigen frequency surpassing 70Hz while mechanical stability better than 30nm through solving key technical problems and conducting experimental test.
