Transverse oscillations of a relativistic electron beam propagating in a beam-induced ion channel have been theoretically investigated and experimentally observed. Good agreement between experimental observations and theoretical calculations strongly suggests that these oscillations may be caused by the ion hose (ion resonance) instability.

    Electron-beam dynamics are calculated for an electron beam propagating parallel to a uniform magnetic field through a periodic ion density channel. Results show that resonant excitation of transverse electron oscillations occurs when the wavelength of the ion density variation equals the axial...
