Abstract

In this work, plasma parameters such as electron density (n_e), electron temperature (T_e), Debye length (λ_D), plasma frequency (f_Plasma), and Debye number (N_D) for Cu plasma produced by Pin-Plate DC discharge were studied. Spectroscopic technique was used to analyze and determine spectral emission lines. The value of the electron density for Cu was in the range (1.5–3.5)×10¹⁸cm^-3 and for the electron temperature was in the range ( 1.31 – 1.61)eV. Finally, plasma parameters of Cu were caculated through plasma produced by Pin-Plate DC discharge using different voltages (600-900) V.
