A laboratory-model bismuth-fueled Hall thruster has been designed, and the geometry of that design has been incorporated into a 2-D radial-axial hybrid Hall thruster simulation. Velocity distribution data from the plume of that simulation, incorporated with calculations based on the known spectroscopy of the bismuth ion, have been used to simulate optical diagnostic measurements of the exhaust velocity of the thruster. Simulated Laser Induced Fluorescence ana emission spectroscopy data has been produced, assuming that the 14681.971 cm-1 transition of ionized bismuth is analyzed. The simulated Laser Induced Fluorescence assumes a narrow line-width, scanning laser probes the plasma either axially or radially, and it is suggested that the fluorescence be collected about the 15146.544 cm-1 transition; emission results have been simulated with varying instrument resolutions and with collection angles at 0° and 60° off the axial axis.
