Efficient algorithms for stochastic Stark-profile calculations

摘要: Abstract Algorithms to compute spectral line shapes including particle dynamics with a stochastic description of the plasma are proposed. Two models yielding different functional forms for shape considered. The proposed algorithms applied argon He-α and He-β lines plus associated lithium like dielectronic satellites at conditions typical inertial confinement fusion experiments. These large-scale ion calculations using methods require significantly less computational effort than corresponding quasi-static conventional approach. It is stressed that do not introduce physical approximations accelerate calculations. In addition, behavior two explored. Finally, examples suggest possible solutions extant discrepancies between theoretical experimental spectra.
