Abstract: Experiments at the University of California, Irvine indicate that a neutralized ion beam (NIB) propagates across a magnetic field in a time scale of less than 1 s without a significant deflection. It is shown for a constant beam density, the nonlinear and the linear diffusion times are too fast and too slow respectively to account for the observed diffusion time. If there is a component of magnetic field normal to the surface of the beam, the Hall term becomes important and the magnetic field penetrates as dispersive whistler waves. For a constant beam density, the penetration time scales with the whistler time rather than the classical diffusion time. A one-dimensional computational calculation, using a Gaussian density profile, shows that as the magnetic field penetrates from a low to a high density region, the magnetic field amplitude grows at a slower rate in comparison with a uniform plasma peak density.Click for full text.
