Figure 4-19: Thrust and current characteristics compared to experimental data and
ID theory. Experimental currents are applied to the emitter for the homogeneous
case. Charge injection boundary condition cases: 1) pref = 10-4 Cm- 3 , Eref =
100 kV/cm, 2) pref = 1-5 Cm- 3 , Eref
1 kV/cm on coarse mesh, 3) pref
10-5 Cm 3
Eref =1 kV /cm on fine mesh.
