Simulation of strongly photoionized silicon plasma

The work demonstrates the process of simulation a strongly photoionized silicon plasma with parameters close to astrophysical. The calculations were carried out within the model of collisional-radiative equilibrium. The obtained results were verified by comparison with the results of other participants of the codes comparison workshop. A comparative analysis of the results with the experimentally measured spectrum of soft X-ray transmission through a layer of photoionized silicon plasma is carried out.
