✦ Synopsis

The suggestion is explored that the two-stream instability has little effect on the propagation of the electron streams which generate type III bursts because the time required (tO for development of the instability is comparable with or greater than the time available (At) for growth of the waves. Inferred parameters for streams in the corona and measured parameters for streams at the orbit of the Earth are compatible with this suggestion. Quasi-linear relaxation, which should occur as the stream forms, ensures that equality t~ = At is set up initially, and restricts the number of escaping electrons to Ns ~ 10 zl. The minimum density requirement on the stream for the two-stream instability to occur is found to be much less restrictive than the requirement that there should be many streaming electrons per Debye sphere.

In situ satellite observations of type III burst exciters at 1 AU show that the beam does not evolve into a plateau in velocity space, contrary to the prediction quasilinear theory. The observations can be explained by a theory that includes mode coupling effects due to excitation of the parametric
