Abstract:

A new approach to computing sheaths of large high-voltage space structures in dense Low Earth OrbitPolar Earth Orbit plasmas is described. The method solves the Poisson equation numerically, using a flexible-finite-element mesh that allows sheath shapes to be described through an extension of the well-known Child-Langmuir-Blodgett 1-D sheath model to three dimensions. Space charge is computed by following trajectories. This approach is potentially more efficient for 3-D sheath and wake problems than other approaches presently available.
