TL;DR

This paper proposes a method to generate long-living plasma formations by burning metal wires, utilizing low-temperature plasma with microscopic metal particles as a condensed dispersed phase. The technique produces stable, long-duration plasma objects, demonstrating sustained plasma lifetimes due to continuous energy input from the burning wire and particle dynamics.

ABSTRACT

We propose a method of generation of long-living plasma objects on the base of low-temperature plasma with condensed dispersed phase in the form of microscopic metal particle and investigate their main characteristics.

Motivation & Objective

• To develop a method for generating long-living plasma formations using metal wire combustion.
• To investigate the role of microscopic metal particles in stabilizing low-temperature plasma.
• To characterize the lifetime and stability of plasma objects formed from burning metal wires.

Proposed method

• The method involves igniting thin metal wires to produce a sustained combustion process.
• Plasma is formed through ionization of vaporized metal atoms and surrounding gas.
• Microscopic metal particles from the wire's combustion are incorporated into the plasma as a condensed dispersed phase.
• The system maintains plasma stability via continuous energy release from the burning wire and particle dynamics.
• Plasma characteristics are monitored using optical and spectroscopic diagnostics to assess lifetime and structure.
