In SRC RF TRINITI investigated implosion of cylindrical and quasi-spherical wire arrays. Such arrays are made of metal wires and plastic fibers both coated by metal. For three-dimensional quasi-spherical arrays implosion the technique was developed to produce wires or fiber with a given distribution of linear mass along the wires. That mass distribution needs for good implosion to the center of array. The wires and fibers was formed by spraying a metal on wire or fiber. We have also developed the technique of manufacture of only tungsten wire with a given distribution of mass per unit length. Flux of emission near the center quasi-spherical array several times greater than the flux of emission for implosion of the cylindrical array. For cylindrical arrays was measured the difference of radiation flux in the radial and axial direction. We investigate the cylindrical conductors through which current flows with linear density 1-3 MA/cm and a rise time of 100 ns. For a cylindrical conductor with a wall thickness of 1 mm electric field on the inner wall was measured. Comparison of the measured and calculated that electrical field developed to evaluate the current carried in the plasma produced on the current flow surface of the conductor. For "Baikal" project the stage of development and state examination of project documentation is completed.
