Scientific paper

A numerical study was conducted on the electron beam-plasma interaction as a possible source for the broadband electrostatic emissions observed in the electron foreshock, with emphasis placed on broadband electrostatic emissions extending to the cutoff frequency of the order of or above 1.5 times the local electron plasma frequency. The values for the beam drift velocity, thermal spread, and density were varied over a range which is consistent with observations, and the effects on the frequency bandwidth over which emissions can grow were examined. Results showed that broadband emissions can be generated by warm electron beams, but a beam density ratio N(beam)/N(plasma) equal to or greater than 0.1 is required, which is 10 times greater than the upper limit ratio inferred from spacecraft observations.
