Abstract :
Problems of visual image formation in the gas-discharge converter (GDC) of X-radiation are discussed. The physical and mathematical model of initial ionization in gas space and development of electron avalanches from ionization centers in pulse electric field is built. The basic processes which affect on parameters of gained images are determined
