Abstract

Summary form only given. The Advanced Test Accelerator (ATA) (50 MeV, 10 kA, 50-ns pulse, 1-Hz repetition rate) has been operated several years with a laser guiding scheme through the accelerator to overcome the beam breaking instability. Growth of transverse beam motion has been controlled by focusing from the laser-produced ion channel, which is somewhat larger than the electron beam. The ATA has also been operated with a higher density ion channel, which has a much smaller diameter than the electron beam. In this mode the ion channel provides strong damping of transverse beam motion by phase-mixed damping with the added cost of beam emittance growth. Predictions of damping rates and emittance mode are compared to experimental observations.
