Titanium K-Shell X-Ray Production from High Velocity Wire Arrays Implosions on the 20-MA Z Accelerator;Physics of Plasmas

摘要

The advent of the 20-MA-Z accelerator has enabled implosions of large diameter, high-wire-number arrays of titanium to begin testing Z-pinch-K-Shell scaling theories. The 2-cm long titanium arrays, which were mounted on a 40-mm diameter, produced between 75 (plus or minus)15 to 125 (plus or minus)20 kJ of K-shell x-rays. Mass scans indicate that, as predicted, higher velocity implosions in the series produced higher x-ray yields. Spectroscopic analyses indicate that these high velocity implosions achieved peak electron temperatures from 2.7 (plus or minus)0.1 to 3.2 (plus or minus) 0.2 KeV and obtained a K-shell emission mass participation of up to 12 percent.
