Abstract
The goal of this work is to study plasma parameters for Fe plasma generated by exploding wire (EEW) in carbon nanotubes-water colloid with three current values (50, 100 and 150)A. In this research, the plasma electron temperature (Te), the electron density (ne), electron density (ne), plasma frequency(f p), Debye length (λD) and Debye number (ND) were found for Fe produced by Arc discharge plasma. Boltzmann plot was used to calculate the plasma electron temperature (Te);electron density (ne) was calculated from Stark broadening. It was found that the electron temperature values increased from (0.4134 _ 0.415) eV and the electron density increased from( 0.93 - 1.16)× 1017cm-3.

Summary
Plasma physicists have commonly used the phenomenon of exploded wires (electro explosion of wires or EEW) for the generation and containment of plasma. Several parameters such as voltage, current pulse, material type, wire dimensions, the medium in. One of the most essential methods used in plasma diagnostics is optical emission spectroscopy In this method, the radiation emitted from the plasma beam is analyzed to determine the plasma parameters. The responses of charged particles (ions and electrons) to decrease the impact of electric fields are applied to Debye shielding. This shielding grants quasi-neutrality special property for, plasma. The number of particles (ND) inside the sphere of Debye can be found from the following equation [7]: ND= 4/3πλ3Dne=1.38×106T3/2/ne1/2( T in K)
