Preliminary R&D of vibrating wire alignment technique for HEPS

The alignment tolerance of multipoles on a girder is better than +/-30 mu m in the storage ring of the High Energy Photon Source (REPS) which will be the next project at IHEP (Institute of High Energy Physics). It is difficult to meet the precision when only using the traditional optical survey method. In order to achieve this goal, a vibrating wire alignment technique with high precision and sensitivity is considered to be used in this project. This paper presents some preliminary research works about theory, scheme design and achievements.
