Abstract:

Analytical methods for deriving space-charge flow solutions are reviewed. Certain exact solutions in which the ions flow in circular trajectories are discussed, and form a natural accel-decel solution suitable for ion guns to be used for ion propulsion. The advantages and the disadvantages of these exact solutions are discussed. The approach to the problem using paraxial solutions is also described. Such paraxial solutions enable the uniformity of current density at the emitting anode to be adjusted. Analytical methods of electrode design are discussed, and it is shown how electrodes can be derived for any analytical space-charge flow solution. Author
