Abstract
Purpose In order to meet the extremely low emittance requirement, the magnets in the storage ring of high-energy photon source (HEPS) need to have a stable support and precise positioning. In HEPS-TF, the key and difficult technologies of HEPS should be researched and developed. Vibrating wire alignment technique is one important project of HEPS-TF. It can be used to pre-align the quadrupoles and sextupoles on one girder with high precision. A vibrating wire measurement system was set up and tested to verify the magnetic center measurement precision and the magnet adjustment error.
