Derived Parameter: Debye Length

Debye Length

The Debye length characterizes the screening range of a charge in a plasma.

$\lambda_{D}=\sqrt{\frac{kT}{4\pi n_e e^{2}}}=6.90\sqrt{\frac{T}{n_e}} \ \ \mathrm{cm}$

where n_e is electron density in cm^-3, and T is in Kelvins.

Debye lengths for quiet Sun (Model 1001; blue), facula (1005; red), and umbra (1006; green).

Model 1005 Debye Lengths (strong facular region)
