Abstract :
A simple one-dimensional account of space charge in an anode-cathode (AK) gap is based on a transit time model. Two limiting cases are treated: thermionic and field emission. Each case is compared to experimental thermionic and field emission data in the literature and the correspondence is shown to be good.
