Advances in Thomson scattering diagnostics of plasmas used for chemical analysis

摘要: Abstract The use of plasmas for chemical analysis is prevalent and new sorts are continually being explored potential applications in this field. However, the underlying mechanisms characteristic processes that occur not completely understood. Free electrons drive reactions, essential to many plasma inherent processes, responsible sustaining discharge while governing kinetic energy transfer between other species. Thomson scattering (TS) a powerful diagnostic technique elucidating fundamental electron parameters number density, temperature, distribution function. TS advantages include providing direct, radially temporally resolved probing free electrons, with little-to-no perturbation plasma, no prior assumptions local thermodynamic equilibrium conditions, simultaneous density/temperature measurements. aim review provide brief explanation theory experimental requirements, as well highlight selected novel instrumentation advances insights about discovered most recent publications, previously covered reviews.
