Webcurrent density is usually chosen to be less than the Child–Langmuir space charge maximum, and an even larger number of apertures are required. This ultimately determines the size of the ion thruster. Figure 5-2 shows a simplified one-dimensional (1-D) view of one of these biased apertures facing the thruster plasma. The Child–Langmuir ...

First proposed by Clement D. Child in 1911, Child's law states that the space-charge-limited current (SCLC) in a plane-parallel vacuum diode varies directly as the three-halves power of the anode voltage and inversely as the square of the distance d separating the cathode and the anode.
