  • Abstract
    A vertical beam instability has been observed for some time in the particle accumulator ring (PAR) of APS. It appears at low beam current when a single linac bunch is selected for PAR injection and is highly reproducible. An investigation was conducted to characterize and understand this instability. We obtained some interesting data and believe this was due to ion trapping. A more stable lattice was established as result of the investigation. This report summarizes the experimental results and gives some preliminary analysis.
