Abstract:

A hollow electron beam produced in a strong axial magnetic field has been extracted into a neutral gas cell where the magnetic field is zero. Due to radial magnetic field in the transition region, the beam rotates and maintains its hollow profile. Equilbrium is provided by the vz x b0 inward force and centrifugal outward force. We have studied both extraction and propagation phenomena in this configuration. Measurements include beam and net currents, beam generated axial magnetic fields, beam rotation and emittance, and light produced. A filamentation instability has been observed outside the magnetic field in this configuration. Beam equilibrium results are also presented and are compared with both experiment and numerical simulation.
