Supersolitons are electrostatic nonlinear structures which have subsidiary extrema in the bipolar electric field signatures. They are known to occur in a plasma with two electron components having different temperatures. In this study we will investigate supersolitons in a plasma consisting of positively charged (stationary) cold ions, a positively charged cold ion beam and cool and hot electrons. The weak beam ions are assumed to drift in the direction of the magnetic field as is the direction of propagation of the solitons. The main focus of the study will be to examine the effect of beam speed and beam concentration on the parametric existence regions of supersolitons.
