  • Abstract
    An instability disruptive to high current main ring operation is the vertical resistive wall instability. Tunes, chromaticities, and feedback loop gains must be continuously adjusted to preserve the beam intensity at injection. Results of frequency and time domain measurements aimed at understanding the sensitivity of the beam to this instability are presented. The influence of selected accelerator parameters is studied in detail. In addition, the effectiveness of various cures is reviewed.<>
