Summary
The magnetosonic wave emission by an intense relativistic electron beam rotating within a plasma is calculated. This process follows the beam trapping as determined earlier, and results in a transfer of approximately half the beam energy to the plasma ions. A nonlinear theory is given in accord with beam and plasma parameters of fusion interest. It is shown that dissipation balances the nonlinearity to produce a shock-type flow resembling that of the linear theory. The primary nonlinear modification is an adjustment of the wave speed to v/sub s/ = V/sub A/M/sub s/, where v/sup 2//sub A/ = B/sub 0//sup 2/4..pi..nm/sub i/ and M/sub s/ = 1 + B/B/sub 0/ is the Mach number (B is the wave field, B/sub 0/ the applied field). Estimates are made of power radiated to the waves and resultant ion energies for some typical experimental parameters.
