The computation of synthetic x-ray spectra emitted by hot plasmas includes Floquet-Liouville formalism based calculation of the Stark line profiles in the presence of the QEF and the radiation transfer through the plasma. The roles of the quadrupole interaction with the ion microfield and of the quadratic Stark effect were studied. Particle-In-Cell (PIC) kinetic simulations were performed to model the QEF inhomogeneity. These theoretical calculations were applied for x-ray spectroscopic analysis of real experiments. The QEF are visualized via satellites emission. The allowance for the quadratic Stark effect is important for consistent interpretation of the experimental results, while the allowance for the quadrupole interaction with the ion microfield does not play a significant role.
