In this paper, we present preliminary successful measurements of the electrical conductivity of weakly nonideal partially ionized complex plasma mixtures generated from dielectric materials. The complex multicomponent partially ionized vapors were generated using an electrothermal plasma source operated in the ablation-controlled arc regime, where the compound dielectric materials were used as the liner of the capillary wall serving as the source of plasma species. The measured discharge current was used in conjunction with the active or pure resistive part of the recorded discharge voltage to calculate the electrical conductivity as a function of time. A comprehensive 1-D time-dependent computer code with radiation transport, which uses the recovered ohmic input power as the only driving force of the computations, was used to report the corresponding plasma state. Measurements in the temperature range of 11000-16200 K and density range of 0.1-25 kg/m3 were performed, and the results were presented, discussed, and compared with theoretical predictions.}, number={8}, journal={IEEE TRANSACTIONS ON PLASMA SCIENCE}, author={Zaghloul, Mofreh R. and Al Na'imi, Miyara S. and Bourham, Mohamed A.}, year={2009}, month={Aug}, pages={1626–1631} }

Such an interplay between theory and experiment is necessary to reduce the number of reasons which might be responsible for the reported discrepancies between theory and experiment, as well as to illuminate the subject of ablation controlled arcs. A consistent methodology for determining detailed composition and thermodynamic functions of the non-ideal plasma generated in such devices is presented and used in the present computations. Different non-ideality effects, due to Debye-Hückel corrections in the Gibbs free energy, which have been ignored in prior publications, have been taken into account. A semi-analytical model for an ET plasma source with non-ideal effects is described and incorporated into a comprehensive computer code to simulate plasma evolution and flow in the discharge capillary. The model is one-dimensional, time dependent and uses the recovered Ohmic power input in the source term of the energy equation. The developed code has been used to investigate the ablation process and has shown the inappropriateness of a widely used ablation model. Code predictions for different plasma parameters are presented, discussed, and compared to available experimental data.}, number={5}, journal={JOURNAL OF PHYSICS D-APPLIED PHYSICS}, author={Zaghloul, MR and Bourham, MA and Doster, JM}, year={2001}, month={Mar}, pages={772–786} }
