Abstract content <br> &nbsp; (Max 300 words)

Using a Particle-In-Cell simulation, the characteristics of electrostatic waves are
investigated in a plasma containing 3 electron components (hot, cold and beam electrons) and a cold ion population. Three electrostatic modes are excited, namely electron plasma, electron acoustic and beam driven waves. These modes have a broad frequency spectrum and have been associated with intense broadband electrostatic noise observed in the Earth’s auroral zone. The growth rates of the beam mode is studied by constructing a growth rate curve from the electric field data. The beam mode is found to have a high growth rate for an intermediate range of wave numbers while it is damped elsewhere.
