# Debye length

From FusionWiki

A plasma consisting of freely moving positively and negatively charged particles has a natural tendency to shield net charges (or cancel DC electric fields).
The effective shielding length is the Debye length, and can be derived from a simple two fluid model of the plasma.

- $ \lambda_D = \left ( \frac{\varepsilon_0 T_e}{e^2 n_0}\right )^{1/2} $

where *T _{e}* is given in energy units.
