Damping Transverse Instabilities in the Tyevatron Using AC Chromaticity

Several papers [1],[2] have suggested possibility of using varying chromaticity to damp the head-tail instability. We test this by cycling the chromaticity sextupole magnets in the Tevatron near the synchrotron frequency to see if the head-tail stability threshold is increased. Further we compare the turn-by-turn evolution of a bunch slice in the pres ence of varying chromaticity to a model previously developed.
