**On-line tool for evaluation of transport coefficients of non-equilibrium atomic plasmas with singly charged ions**

Programmers: N. A. Almeida and S. M. Benilov

The tool evaluates:

- Coefficients of the Stefan-Maxwell equations and expressions for the heat fluxes in non-equilibrium atomic plasmas with singly charges ions. Formulas [1] are used.

- Coefficients of Ohm’s law, translational thermal conductivities of the electron and heavy-particle gases, and reactive thermal conductivities) in 2T ionization-equilibrium or LTE atomic plasmas with singly charges ions. Formulas [2] are used.

The output is generated in the form of tables. The present version of the code works for the following plasma-producing gases: argon, xenon, and mercury.
