• A light ion beam (LIB) is considered as a good driver for inertial confiment fusion, and necessary to propagate a few meters from the diode to a target. Usually we expect the complete charge and current neutralization by the aid of a plasma channel. Ottinger et al. have analyzed a stability of a beam-plasma system under the same assumption. However, in this case, the effect of a finite beam length is ignored. Thus, we must reconsider the assumtion of the charge and the current neutralization, particularly, on the head and the tail of the beam. We take a finite beam length into consideration and propose a new model of a beam- plasma system. The stability analysis is done by investigating the dispersion relation in this model. The incompleteness of the current neutralization on the both ends is important for the growth rate of the instability.
