“…In the recent two decades EBA phenomenon finds use in different areas of science and technologies [5,[9][10][11][12][13][14][15][16][17][18][19][20]. At the present time EBA is considered as one of alternatives to pulsed laser ablation (LA) which is more advanced.…”

“…Of course the physical mechanisms of excitation and formation of plasma plumes for the processes LA and EBA have their special features; however, phenomenology of both processes, and in particular, the plasma density and also the dynamics of formation and dispersion of plasmoid (plume) are sufficiently close [5].…”

“…PEBA offers numerous advantages over other conventional techniques, e.g., versatile setup, congruent material transfer from bulk to film under optimum conditions, low cost, and small footprint. One of the most attractive features of PEBA is the possibility of fabricating films under non-thermal conditions [1][2][3]. During PEBA, an intense electron pulse (~100 ns) strikes the target surface, triggering a sequence of strongly coupled processes.…”

Pulsed electron beam ablation (PEBA) has proven to be a promising and powerful technique for the growth of high quality thin films. Pulsed electron beam film deposition consists of many physical processes including target material heating, target ablation, plasma plume expansion, and film growth on a substrate. Plasma plume expansion into a vacuum or an ambient gas is a fundamental issue in PEBA as the quality of thin films deposited onto the substrate depends on the composition, energy and density of particles ejected from the target. In the present study, gas-dynamics equations are solved to investigate plasma expansion induced by interaction of a nanosecond electron beam pulse (~100 ns) with a graphite target in an argon atmosphere at reduced pressure. The spatio-temporal profiles of the temperature, pressure, velocity, and density of the plasma plume are numerically simulated for a beam efficiency of 0.6 and accelerating voltage of 15 kV. The preliminary results show a rich variety of behaviors. The model is validated by comparing some of the obtained simulation results with experimental data available in the literature.

The electron beam ablation phenomenon is investigated on the basis of the general thermodynamic representations about power balance of absorption and dissipation energy processes in conditions of interaction of the concentrated energy flux with a condensed substance. It is shown that at high levels of absorbed power density, exceeding energy dissipation speed by the heat conductivity mechanism, the fast phase transition of a condensed substance in dense plasma can take place (© 2012 WILEY‐VCH Verlag GmbH & Co.
