Abstract

This work elucidates the evolution of Arc plasma and its characterization in terms of different plasma parameters under atmospheric pressure. The I-V traits of Langmuir probes are plotted from the experiment for a single probe approach in Arc plasma. It is discovered that the silica seed alters the electron temperature of the plasma substantially, while the temperature of the gas in the surrounding remains nearly unchanged. The single probe traits were applied to find the electron temperature, floating potential, Debye length and electron density. It is perceived that electron density increases substantially, while electron temperature is reduced after seeding the Arc plasma. A large fall in electron temperature an unusual growth in electron density which is discovered after mixing the plasma with silica aggregate in comparison to those before mixing. The effect of discharge voltage on plasma frequency and Debye length is also mentioned.
