主　　题：periodic electrical foils 

摘      要：The results of a study of the electrical explosion of aluminum foils with an artificial periodic surface structure created by laser engraving are *** were carried out on pulsed high-current generators BIN(270 kA,300 kV,100 ns)and KING(200 kA,40 kV,200 ns)with Al foil of thicknesses 16 and 4μm,*** of the exploded foils were recorded by point projection radiography in the radiation from hybrid *** is found that the application of an artificial periodic structure to the foil leads to a much more uniform and well-defined periodic structure of the exploded *** recorded in the UV range using a microchannel-plate-intensified detector show that the radiation from a surface-modified foil is more uniform along the entire length and width of the foil than that from a foil without modification.
