“…The aspect ratio of measured craters, i.e. the ratio of the crater's diameter to its depth, varied from ∼ 27 (smaller craters) to ∼ 5 (larger craters), the corresponding interpolation gave dependance D cr /P cr = 130 · D cr [mm] −1.6259 for aspect ratio and 3 ] 0.2821 for crater diameter. From examination of the blastshield it was found that several smaller craters contained remains of shrapnel sealed in the glass.…”

“…The failure of ignition of the fast ignition targets with the cones and the non-ignition experiments with such target can result in the formation of striking cores [3]. They arise due to collapse of the metal cones, hemispheres and parts having some other shapes toward their axes with velocities that are not sufficient for formation of cumulative jets (see Refs.…”

“…They arise due to collapse of the metal cones, hemispheres and parts having some other shapes toward their axes with velocities that are not sufficient for formation of cumulative jets (see Refs. [3,[15][16][17]). The limitation on the velocity of collapse seems to restrict the maximum velocity of the striking cores, that can arise in the IFE experiments, by the value of about 3 to 5 km/s.…”

“…Operation of the Inertial Fusion Energy (IFE) power plants and the experiments related to IFE can be accompanied by the formation of the high-velocity, high-density objects that can damage optical elements and/or other equipment unless some measures to prevent this are not taken [1][2][3][4][5]. In many situations the effect of such objects on the equipment will be similar to that of the micrometeorites and space debris on the equipment operating in space.…”

Abstract. Analysis of the damage caused by laser plasma accelerated fragments of metal target was performed. Measured as well as calculated parameters of craters and shrapnel found in BK7 glass blastshield are presented. Method applied for the measurement of parameters of craters is described. Potential damage of optical elements by the so-called striking cores (high-velocity stable objects arising due to collapse of cones or some other target parts toward their axes) that can be generated in IFE related experiments is evaluated.
