Electrical currents in the plasma provide the simplest and most common way to get structures. The irregularities are then said to result from a two-stream instability. ... Sometimes the currents are not strong enough to destabilize the plasma by themselves, and we must add density gradient densities to the picture. In that case we are dealing with a gradient-drift instability.  3, fiche 1, Anglais, - two%2Dstream%20instability
