  In the pre­sent ar­ti­cle a com­plex of tech­no­log­i­cal so­lu­tions based on 6/3.5 MeV pulse-to-pulse lin­ear ac­cel­er­a­tor, de­tec­tors made of CWO scin­til­la­tors cou­pled with PIN pho­to­di­odes and image pro­cess­ing al­go­rithms pro­posed. En­er­gies, dose rate and other pa­ra­me­ters of ac­cel­er­a­tor were op­ti­mized to reach high per­for­mance of the x-ray sys­tem and to carry out ro­bust and re­li­able ma­te­r­ial dis­crim­i­na­tion in the mass thick­ness range up to 120 g/cm2 at least. Eval­u­a­tion of ef­fec­tive atomic num­ber of ma­te­ri­als of main three groups (or­gan­ics, min­eral/light met­als, met­als) was ful­filled with pre­cise­ness ±1 for the op­ti­mal mass thick­ness range at the scan­ning speed 60 cm/s. In­stru­ment for eval­u­a­tion of phys­i­cal mass of the sep­a­rate ob­jects on the image is pro­posed and re­al­ized.
