Abstract:

The linear properties and saturation mechanisms of the lower-hybrid drift instability have been investigated using a one-dimensional particle-hybrid simulation. For low drift velocities V sub d much less than V sub ti, ion trapping and current relaxation V sub d approaches limit of 0 are competing processes for stabilization. If the relative electron-ion drift velocity is kept constant in time, ion trapping causes the end of instability growth if this drift is allowed to decrease consistent with momentum balance, then saturation is due to current relaxation.
