It is used to adjust the transverse tunes with a small impact on the beam dynamics. A global tune knob is designed for the Hefei Light Source (HLS). In the tune knob, the quadrupoles are grouped into four families and are symmetrically adjusted. Methodical Accelerator Design-X (MAD-X) is used to calculate the coefficients of the tune knob and the Accelerator Toolbox (AT) is used to double check the accuracy of the tune knob. The chromaticity is corrected by the sextupoles in the storage ring. This paper reports preliminary simulation results of the tune knob for HLS. The beta function deviations are also studied.
