METHOD OF DETERMINING THE PARAMETERS OF THE NEUTRAL AND ELECTRONIC COMPONENTS OF THE NON-EQUILIBRIUM PLASMA Russian patent published in 2018 - IPC H05H1/24 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of plasma diagnostics and can be used for studies of nonequilibrium anisotropic plasma directly under the operating conditions of a wide range of gas discharge devices: lasers, plasma torches, light sources, powerful current and voltage stabilizers, key elements, inverters. In the investigated plasma object, the second derivative of the CVC of a cylindrical probe is recorded, by sharing the experimental data and solving the Boltzmann kinetic equation, the energy dependences of Legendre components of the FRES ƒ₀, ƒ₁ and ƒ₂ and the electron-atom collision integral S₁ at the same time perform an accurate measurement of the gas pressure p and the electric field strength E_z. Method provides a determination of the temperature T_a of the neutral plasma component and the parameters of the electron component - the transport cross section of electron-atom collisions and the convective electron velocity 〈v〉_con.

EFFECT: technical result is the determination of the set of parameters of the neutral (local temperature) and electron (electron-atom transport cross-section and convective velocity) plasma component.
