Abstract
X-ray diffraction of particle fluxes formed by shaped charges with a combined steel liner consisting of a hemisphere and a cylinder with a hemispherical part of degressive thickness (decreasing from top to bottom). It has been found experimentally that the transition from a constant to a degressive thickness of the hemispherical part increases the velocity of the head portion of the jet flow of the liner material formed during its compression, which is subsequently cut off during collapse of the cylindrical part. The maximum velocity of the particles obtained as a result of <cutoffs> in experiments was 8.6 km/s.
