Consider a one-dimensional space-charge limited accelerator operating on cesium with the accelerating gap xa=5 mm, the accelerating voltage V0=37.5 kV, and the cross- sectional area A=0.01 m2. Calculate the maximal current density (j) and the total current (I) that can be drawn through the accelerator, the jet's power density (P/A) and the total power of the jet (P), the thrust density (T/A) and the total thrust (T). If the specific mass of power plant is 10 kg/kW, what is the maximal attainable acceleration of a spacecraft propelled by this thruster
