“…Most probable velocity of ions in colliding plume is observed lower than that of single plume at each pressure as shown in Figure 6 b which is attributed to retardation caused by ion-ion collisions of two seed plumes. We see that expansion of plasma and hence ionic species depends upon the ambient gas and its pressure [ 11 , 39 , 40 ]. Plume expansion in different pressure regime is characterized by the plume length.…”

“…There have been reports of using carbon ion beam therapy, as heavy carbon ion deposits more energy to tumour tissue and is more effective in destroying the tumour tissue compared to protons [ 7 ]. Recently the scientific community have shown their interest towards the interaction of two plasma plumes known as colliding plumes [ 3 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]Colliding plasma plume is of particular interest as compared to single plume as it has found its potential applications in droplet free thin film deposition, getting an ionic beam (since stagnation evolution is dominantly single species), inertial confinement fusion, and approximations to astrophysical plasma [ 8 , 14 , 15 , 16 ]. Various target configurations have been used for the study of colliding plasma plumes e.g.…”

“…In general, the expansion velocity depends inter alia on the vacuum condition and its surrounding medium, but usually is in the range 10 6-7 cm/s [23]. The processes inside a laser-produced plasma have a wide dynamic range with typical time scales on the order of nanoseconds [24]. The expansion dynamics of the plasma was recorded using the available fast-gated visible camera based on a 10ns gate time, additionally, the images were captured as a function of time in 10ns steps.…”

The colliding laser-produced plasma (CLPP) has a wide range of applications in various contexts, that might start with astrophysical applications or pulsed laser deposition or Laser-Induced Breakdown Spectroscopy (LIBS), which is a powerful analytical technique for elemental analysis and material identification. In CLPP experiments, the stagnation layer might form at the interface region when two dense laser-induced plasmas collide, and the degree of stagnation can be diagnosed by the collisionality parameter that is used to determine what kind of interaction will take place, i.e., soft or hard stagnation. Our experimental work presents the results of the temporal, spatial and semi-spectrally imaging of colliding plasmas of aluminium and silicon targets. The analysis is focused on describing the velocity of the expanding plasma front for the interaction zone. The aim of the work presented here is to further advance and study colliding plasma techniques, as well as other methods to realize and control species density and expansion, with a view to a deep understanding of these complex mechanisms and optimising emission in the visible wavelength range. All investigation sequences were based on a similar experimental setup, where two different focusing lenses were used with an effective focal length (EFL) of approx. 100mm or 125mm to achieve seed separation around 1.66mm or 2.16mm, respectively. Time-resolved emission imaging was employed to track the stagnation layer‛s size and shape, which might act as a signature of hard versus soft stagnation. The study provides a considerable amount of detailed data related to the expansion velocity of the interaction zone which extends the understanding of the behaviour of particular species within colliding laser-produced plasmas.

“…Finally, MSE data have been useful for investigations like initiation of a formation of an arc at a plasma-wall contact [160] and quick creation of approximate spectra of dense cool plasmas in the optical wavelength range [161]. Data from [87] have been used in papers dealing with propagation distance-resolved characteristics of filament-induced Cu plasma [162], heterogeneous (Cu-Ti) colliding plasma dynamic [163] and initiation process of vacuum breakdown between copper u and copper-chrome electrodes [164]. Data from [17] have been used in a paper dealing with the zone of compression of a magnetoplasma compressor as a source of extreme ultraviolet radiation [165].…”

The aim of this paper is to analyze the various uses of Stark broadening data for non-hydrogenic lines emitted from plasma, obtained with the modified semiempirical method formulated 40 years ago (1980), which are continuously implemented in the STARK-B database. In such a way one can identify research fields where they are applied and better see the needs of users in order to better plan future work. This is done by analysis of citations of the modified semiempirical method and the corresponding data in international scientific journals, excluding cases when they are used for comparison with other experimental or theoretical Stark broadening data or for development of the theory of Stark broadening. On the basis of our analysis, one can conclude that the principal applications of such data are in astronomy (white dwarfs, A and B stars, and opacity), investigations of laser produced plasmas, laser design and optimization and their applications in industry and technology (ablation, laser melting, deposition, plasma during electrolytic oxidation, laser micro sintering), as well as for the determination of radiative properties of various plasmas, plasma diagnostics, and investigations of regularities and systematic trends of Stark broadening parameters.
