“…Inline расчеты таких характеристик, как правило, невозможны ввиду больших временных затрат, поэтому обычно при расчетах используют заранее вычисленные таблицы для некоторых предельных случаев с использованием интерполяции между ними [6,7].…”

“…The number of ion states that must be taken into account can be very large. To reduce the system of kinetic equations we apply a radiative unresolved spectra atomic model (RUSAM) (Kim et al, 2012;Novikov et al, 2010). Knowing the concentrations x ks the tables of spectral absorption coefficients and emissivities are obtained with the code THER-MOS (Nikiforov et al, 2005).…”

The irradiation of thin films by intensive subpicosecond laser pulses with nanosecond prepulse is accompanied by a number of various physical processes. The laser beam transmissions through the film as well as the re-emission flux on both sides of the film plasma have been evaluated by simulation for Al and CH2 materials. It has been demonstrated that the thickness of the film can be chosen to cut off the long nanosecond prepulse whereas the main pulse is transmitted through the plasma. Thus, thin films can be useful for the laser contrast improvement in experiments with different targets.Nevertheless, the laser energy transformation into the soft X-ray radiation on the back side of the shielding film plasma can reach up to 7% of the incident intensity for the Al film and result in strong preheating of the target. At the same time the re-emission flux produced by a CH2 film is an order lower than that in the case of Al film. The shielding of an Ag bulk target by Al and CH2 films is simulated and discussed.

Сравнение и анализ спектров плазмы железа (по материалам семинара NLTE9) В работе представлены результаты сравнения характеристик плазмы железа, полученных по итогам семинара по неравновесной плазме NLTE9, который проводился в Париже, Франция, в 2015 г. В семинаре приняли участие более 20 кодов из 9 стран, в том числе программный комплекс THERMOS от ИПМ им. М.В. Келдыша РАН. Приводится краткий обзор кодов, принявших участие в семинаре, а также сравнение различных характеристик плазмы для нескольких расчетных случаев. Ключевые слова: неравновесная плазма, программа THERMOS Anna Dmitrievna Solomyannaya, Ilia Yurievich Vichev Comparison and analysis of the iron plasma spectra (based on the NLTE9 workshop) The results of the comparison of iron plasma characteristics obtained on the basis of the NLTE9 workshop, which was held in Paris, France, in 2015. The meeting was attended by more than 20 codes from 9 countries including code THERMOS from Keldysh Institute of Applied Mathematics RAS. The paper provides a brief overview of codes and comparison of the plasma characteristics for several cases.
