A low frequency instability (Ωi<ω<Ωe) observed in an electron-beam-plasma system has been investigated. This instability is caused by unneutralized space charge from the perpendicularly propagating ion-acoustic wave. The dynamic stabilization of this instability by a high frequency (-ωpe) electron wave is also investigated.
