The source divergence analysis will be completed in December. Objectives of the upcoming target series are to correlate hohlraum temperature and lithium intensity and to compare target behavior with hydrodynamic modeling. Work to provide improved diagnostics is proceeding. A cylindrical target with no bottom hole will allow use of a witness plate thermal diagnostic. Also, multiple shocks were not detected on the wedge-shaped shots.
Spectral data collected now show intense C, O, and H lines during most of the power pulse.
MgF 2 -coated elliptical mirrors are responsible for these enhancements to the VUV spectroscopy. We are concentrating on anode plasma line width measurements for divergence studies. The aluminum thickness in Gamble-II ion diode experiments at NRL with the exploding metal foil anode plasma source is being optimized. Aluminum is vaporized at lower current levels than expected. The baseline capacitor size has been selected.
