| Abstract: | A generalized equation, which governs space charge current flow in three relativistic configurations, was derived from Poisson's equation with assumption of space charge limited flow. A method for solution to the equation was introduced and the characteristic of solution for the three configurations was discussed as well. It was found that the expressions of space charge limited flow for both the common vertex coaxial circular cones and coaxial cylindrical conductors have polarity effect, which results in different distribution of space charge and electrical stress from that of planar case. |
