Abstract
The Vp X B acceleration scheme with use of a transverse electromagnetic wave is demonstrated experimentally. However, in order to couple particles with the transverse wave, a slow-wave structure has to be employed because of low electron beam velocity. When the electron beam propagated through the slow-wave structure composed of dielectric-loaded slab-symmetric waveguide in the present paper, an orbit of the beam because unstable. We have observed the electron beam instability to investigate its mechanisms. As a result, an electron beam in the dielectric-loaded waveguide is deflected to the opposite direction from the material on the waveguide wall. By adding the beam-generated plasma in the slow-wave structure the electron beam has been observe dot become stable.
