1. In this section we describe the dispersion characteristics of the three wave modes identified in the previous paper for a plasma at T = 6000 K drawing a current density of J = 1 x IO5 Ah 2. This current density is typical of the current densities expected in low power arcjet thrusters. Table 2. shows the steady state property values and conditions employed in the computation. Figures 3-5 show the dispersion curves of the three wave modes, and Figures 6-8 show the corresponding growth rates forthe three modes.
