TITLE
Study of ablation front for laser plasma experiment of stellar opacity measurement
ABSTRACT
The proposed doctorate thesis is to be done within the framework of a project aiming at testing the technique of double ablation front to
heat and compress targets on an experiment to be performed in 2016 at the LLE/OMEGA laser facility in Rochester, USA. Our project is
motivated by recent results of seismic investigations of stellar interiors, which have put in evidence inconsistencies in the stellar evolution
models and in the laboratory experiments. We intend, following the hydrodynamics simulations we performed to design opacity
experiments with the double ablation front technique in planar geometry. If successful, this experiment will serve as a basis for LMJPETAL proposals. The student will take part in the preparation of the experiment by running hydrodynamics simulations in the chosen
experimental configuration to be done with the CHIC code (CELIA Hydrodynamics & Implosion Code), which will help designing the
targets to be used. Afterwards, he/she will take part in the running of the experiment and do the data analysis and interpretation. The
physics interpretation of the experiment will be done within the framework of plasma atomic physics models.
