摘要
The spatial profiles of implosion core temperature and density are very important to check the theoretical simulation codes and understand the implosion physics in depth. A method is presented that the temperature and density profiles are evaluated by multi-objective optimization, where the normalized intensity profile is calculated from implosion core X-ray images. Two models, i.e., the model with considering absorption and the model without considering absorption, are studied. The results indicate that the temperature profile from the model without considering absorption is about twice that from the model with considering absorption. The density profiles evaluated by the two models are almost the same in the fuel zone, but the density from the model without considering absorption is more than ten times smaller than that from the model with considering absorption in the ablator zone.
