Determination of Characteristics of the Torch Discharge Plasma Burning in a Mixture of Atomic and Molecular Gases

The present article shows the results of temperature measurements of electrons and gas of the torch discharge burning in the mixture of argon and air. The study established the insignificant effect of added air on the characteristics of argon plasma and evaluated the conductivity of the plasma torch discharge burning in the mixture of argon and air.

The ignition brachystochrone

The path is sought in the temperature–density plane that allows desired plasma burning conditions to be reached in the shortest possible time. This task is undertaken using the tools of classical variational analysis. The derived expression of Euler's equation is found to be degenerate. Ways to overcome such an impasse are examined, and eventually the solution is obtained. Illustrative applications to the OMITRON proposed ignition experiment are presented, which make reference to the Lackner–Gottardi and ITER-P89 scalings for the energy confinement time.
