Finite-length effects on cylindrical Langmuir probes
Sigvald Marholm, R. Marchand
Abstract
This work uses self-consistent 3D kinetic simulations to quantify and profile currents collected along a Langmuir probe. These results can be used to design optimal probes for a wide range of parameters relevant to the ionosphere, and low density laboratory plasma experiments.
