| Popis: |
Computer simulations of magnetosonic waves, velocity-shell instabilities, and upper-hybrid heating show evidence of a general damping mechanism for large-amplitude electrostatic waves propagating perpendicular to a magnetic field: Particles trapped by a wave of frequency $\ensuremath{\omega}$ and phase velocity ${V}_{\mathrm{ph}}$ see an electric field ${V}_{\mathrm{ph}}\ifmmode\times\else\texttimes\fi{}B$, which accelerates them parallel to the wave front until the $v\ifmmode\times\else\texttimes\fi{}B$ force is large enough for detrapping. For $\ensuremath{\omega}\ensuremath{\gg}{\ensuremath{\omega}}_{c}$, velocities as large as $(\frac{\ensuremath{\omega}}{4{\ensuremath{\omega}}_{c}}){V}_{\mathrm{ph}}$ can be attained, within a time ${\ensuremath{\omega}}_{c}t\ensuremath{\approx}\frac{\ensuremath{\omega}}{4{\ensuremath{\omega}}_{c}}$. |
