Advanced Cold X-Ray Source Program
Abstract
This report, the final technical report for the Advanced Cold X-Ray Source Program, describes experimental research efforts to develop plasma radiation sources (PRS) for the simulation of cold x-ray effects. On the Double-EAGLE generator we have investigated four advanced PRS loads: large-diameter aluminum wire array, aluminum/ magnesium wire array, argon/titanium puff-on-wire, and aluminum/titanium wire array. On the Saturn generator we have investigated aluminum/magnesium wire arrays and aluminum/potassium-chloride wire arrays. The large-diameter aluminum arrays demonstrated a K-shell x-ray yield of 50 kJ, a 50% increase over previous results; return current symmetry plays a key role for large diameter implosions. The aluminum/magnesium wire arrays demonstrated a 20% increase in yield over that of pure aluminum; the enhanced yield is due to a combination of opacity and startup effects. The argon/titanium and aluminum/titanium loads both ionized the titanium into the He-like state and produced titanium K-shell x-ray yields of > 1 kJ. For the Saturn experiments, the magnesium/aluminum arrays confirmed the increase in K-shell yield; addition of KCI did not significantly increase the yield above 2.7 keV.
