Abstract :
To verify the codes which describe implosion of wire conical wire arrays with a mass of 200-400μg and large and small radii of cone 12-20mm and 5-10mm, correspondingly, were used. In spite of the fact that these liners produce a less powerful pulse of X-radiation than cylindrical ones, they have some features especially important to verify codes. For a cone angle of >; 20° the X-pulse has three peaks. Comparison of their relative magnitude and duration obtained by experiment and in calculations allows us to more reliably verify some assumptions introduced into the code than would be the case of cylindrical liners. At the Angara-5-1 facility due to the electrostatic stretching of the cylindrical wire array occurred by an additional electrode the quasi-spherical arrays of 30-6- tungsten wires 6μm thick are formed with a radius of 8-12mm and a mass of 200-400μg. The implosion of Z pinches formed with such liners was effected by 3-4 MA current with a rise front of 100ns at the Angara-5-1 facility. It was shown that the central part of such a liner forms a hotter area compared with its edges and a hotter one than in the case of cylindrical liners.
