X-Ray Radiation Power Optimization In 1 Ma To 4 Ma Wire-Array Implosions

Tungsten wire array implosions driven by 1 MA to 4 MA current were experimentally investigated. X-ray radiation power was improved through load parameters optimization, electrode structure improvement and well control of initial array conditions. The maximum powers of 5.3 +/- 1.0 TW and 5.6 +/- 1.1 TW, the highest at the 3 MA to 4 MA current level up to now, were measured in the single array and the double array implosions, respectively.
