Therefore, by measuring the spectral line shapes, it is possible to deduce such fundamental plasma parameters as temperature and density, as well as more involved characteristics like velocity distributions, presence of electric and magnetic fields etc. This is the simplest mechanism of line broadening, caused by the thermal motion of the light emitting particles. There are limit cases, when one of these dominates, but evidently, there are many conditions between these limit cases. In the opposite case, the high-density regime, the plasma screening is almost entirely effective, and the main source of line broadening is the micro fields generated by the charges of the chaotically moving particles. Space inhomogenities in the plasma parameters cause the formations and propagation of waves in the plasma.
Turbulent fields can also develop in the plasma.
The turbulent fields in plasma received recently wide attention by researchers, both theoreticians and experimentalists. The data derived from the spectral measurements, can be very complicated and, usually, there is no straightforward way to infer the plasma parameters directly. Thus, we need to be able to calculate the spectra either analythically or using computer simulations and then compare them to the observed data in order to determine plasma properties. The CR calculation of ionization composition in each plasma mass cell provides correct description of transport phenomena in non-equilibrium media. Direct account of unisotrpic radiation field in atomic kinetics allows for rigorous treatment of fine effects like lasing or pumping by external radiation source.
