Karazin popup.description2 The objects of the study are charged and neutral particles in the dusty molecular plasma, at an electrical breakdown in the atmosphere of Mars; quartz glass and Polissya amber under the action of ionizing radiation. The purpose of this stage is the study of C2H2 and Ar/C2H2 gas discharges with dust particles in the kinetic approximation; the development of kinetic theory of electrical breakdown in CO2/ N2 /Ar environment for the conditions corresponding to the dusty storms on Mars; the investigation of luminescence spectra of quartz glass and Polissya amber during X-ray irradiation. Theoretical and numerical models for C2H2 and Ar/C2H2 gas discharges with dust particles are developed in kinetic approximation and properties of the plasmas are studied. It is determined how the densities of charged and neutral species and the effective electron temperature in argon-acetylene plasma depend on the electron density, input flux of acetylene and dust density. It is developed a kinetic theory for an electrical breakdown in CO2/ N2 /Ar environment for the conditions corresponding to the dusty storms on Mars. The properties of the environment, including effects of dust particles on the electron energy distribution function, are studied. Changes in the structure and energies of electronic transitions of amorphous substances such as quartz glass and Polissya amber under the action of long-term irradiation by X-ray quanta with energies up to 60 keV are also investigated.
