Description
In the commissioning of the High Energy Photon Source (HEPS) from 2024 on, we have completed the testing of slow orbit feedback system (SOFB). The slow feedback system has achieved stable operation in conjunction with high-frequency feedback, successfully adhering to the 1 Hz design target and effectively controlling long-term orbit drift. MOFB system up to 40Hz was also developed, and it has been proven to effectively reduce mutual interference when there are variations in the gaps of different beamlines. This paper will present the source of orbit drift at HEPS first, the system structure of system, then a detailed account of the issues encountered during the SOFB and MOFB commissioning process, the solutions implemented, and the actual effects observed in the following stable operation.
