The Advanced Test Accelerator (ATA) beam is guided in a low density ion channel produced in benzene gas by a KrF laser. The strength of the ion channel has been measured by deflecting the electron beam in a steady transverse magnetic field. After emerging from the magnetic field, the beam oscillates transversely inside the channel with a few mm amplitude. The transverse position of the beam is measured at many positions using the wall current monitors. The wavelength of the oscillation is measured from a plot of transverse position vs propagation distance. With a 0.5 J laser pulse and 4 x 10/sup -4/ Torr benzene pressure the wavelength was 1 m corresponding to 90 esu/cm/sup 3/ with ..gamma.. = 84.
