Abstract :
In this work, we describe the characterization of emission under the assumptions that the emission site radii are log-normal distributed and that adsorbates increase the work function. Statistical factors are required to generalization single tip theory to array current estimates via the Statistical Hyperbolic Model. The simulation methods are for characterizing coated emitters being developed for satellite Electric Propulsion and Electrodynamic Tethers devices
