Zusammenfassung:Summary form only given, as follows. A description of a simple X-ray unit with effective radiation energy of 80 keV and pulse duration of /spl sim/15 ns of FWHL is presented in the paper. The unit design is based on a serially produced nanosecond high-voltage generator, synchronized with a precision of /spl sim/10 ns. Issues of unit radiation head and cassette with the film protection in the conditions of explosive experiments are considered. Radiography results of cumulative jets and deformation of metal shells in experiments with HE-charges are presented. In the first case the subject was formed under the influence of HE-charge with the weight from several tens up to hundreds of grams and represented quasi-metal jet with the diameter of about 1 mm and close to copper density, moving with the velocity of several kilometers per second. In the second case the behavior of design elements of magnetocumulative generators, aluminum tubes of /spl sim/25 mm diameter and wall thickness of 3 - 4 mm in particular, at explosion of several tens grams of HE-charge, was studied. The possibilities of organization of multi-frame shooting of different process stages in one experiment are discussed.
