We have designed and produced hot, millimeter-scale, high-{ital Z} plasmas of interest for National Ignition Facility hohlraum target design. Using a high-{ital Z} gas fill produces electron temperatures in the 3.5{endash}6-keV range, the highest temperatures measured to date for high-density (10{sup 21} e/cm{sup 3}) laser-heated plasmas, and much higher than the 3 keV found for low-{ital Z} (neopentane) fills. These measurements are in good agreement with the target design calculations, and the {ital L}-shell spectroscopic approach used to estimate the electron temperature has certain advantages over traditional {ital K}-shell approaches. {copyright} {ital 1999} {ital The American Physical Society} more...
