Calculation of plasma parameters resulting from the wires-exploding technique of copper material

Abstract EN

In this research the diagnostic of optical emission spectroscopy from exploding copper wires have done by change of wire diameter.

By using Boltzman plot can be calculated the plasma electron temperature ??, and by using Stark broadening can be evaluated the electron density ?? for different copper wire diameter (0.2, 0.25 and 0.3) mm at current 75 A in deionized water.

It was observed that the electron density ?? decrease with an increasing wire diameter from 0.2 mm to 0.3 mm while the electron temperatures increase for the same wire diameter.

The plasma has a peak 652 nm corresponding to Hα line for .hydrogen .atoms which obtained from .optical emission spectrum (OES), the peaks belong to atomic copper lines.

The plasma electron temperature related with emission line intensity and number .density with the formed copper nanoparticles size was studied.
