“…In the storage rings, the betatron tune is the number of transverse oscillation periods in one turn. Betatron tune should avoid critical resonance lines and remain stable for user operation [8]. In the synchrotron light source storage ring, the tune reflects the number of transverse oscillations of the beam in each gyration cycle, and the stability of the tune directly affects beam stability.…”

The theory of tune feedback correction and the principle of a feedback algorithm based on machine learning are introduced, with a focus on the application of lasso regression for tune feedback correction. Simulation verification and online feedback correction results are presented. The results show that, after applying machine learning, the feedback accuracy of the tune feedback system was higher, and the betatron tune stability was further improved.
