Notes:
We have successfully employed isoelectronic line ratios to measure the electron temperature in gas-filled hohlraums and "gas bags'' shot with the Nova laser. Isoelectronic line ratios are well suited to this measurement because they are relatively insensitive to radiation field effects (in hohlraums), opacity, transients, and variations in electron density compared to conventional line ratios. Targets were designed to produce plasma parameters Te∼3 keV and Ne∼1021 cm−3 over a scale length of ∼2 mm. Collisional-radiative, transient K-shell atomic kinetics calculations including line transfer were performed by post-processing the Lasnex results. By comparing these calculations with experimental data, we infer electron temperatures of at least 3 keV for both types of targets. © 1995 American Institute of Physics.
