Abstract
A detailed computer model has been used to simulate plasma kinetics and lasing behavior during the excitation phase of discharge current, also known as phantom current. Results indicate that the phantom current can indeed be attributed to the acceleration and drift of the pre-pulse electrons which occurs as the electron temperature is raised to approx. 2-3eV corresponding to the threshold energies required for excitation of Cu states. The phantom current also coincides with a local minimum of the plasma resistivity which occurs as a result of the complex interplay between the electron temperature and the overall electron-heavy particle collision frequency. These results are compared with experimental data for I-V characteristics, radially and time resolved hook population densities for selected Cu I states, electron densities, and laser pulse intensities.
