Abstract
The transverse tune of the beam in a synchrotron will fluctuate due to the main quadrupole power supply ripple, which leads the spill ripple through the variation of the separatrices area. To reduce the spill ripple, an additional pair of fast-response quadrupoles (FQ) is adopted to compensate for the tune ripple caused by the main quadrupoles. After using the FQ feedback, the amplitude of the spill ripple with a frequency of less than 800 Hz has been reduced to a tenth of that in the normal mode.
