Ion acoustic lower hybrid resonance
WebThe origin of lower hybrid resonance noise discovered by the Alouette I satellite is discussed. It is shown that in the ionosphere there are electrostatic waves propagating at … In plasma physics, a lower hybrid oscillation is a longitudinal oscillation of ions and electrons in a magnetized plasma. The direction of propagation must be very nearly perpendicular to the stationary magnetic field, within about √me/mi radians. Otherwise the electrons can move along the field lines fast enough to shield the oscillations in potential. The frequency of oscillation is ,
