The main objective of the internship is to study the effects of various physical processes on the operation of these high gain targets. We will start by getting to grips with the 1D radiative hydrodynamics simulation code as well as the associated analysis tools and from the existing operating points, we will search for new gain operating points. Then, we will focus on the effect of fundamental processes on the release of energy such as, for example, ‘ShineThrough’ which is the process of transmitting laser energy, at very short times, or even the stopping power of charged particles when the target releases energy. In accordance with the commitments made by the CEA in favor of the integration of people with disabilities, this job is open to everyone. Participating in national protection, an administrative investigation is carried out for all CEA employees in order to ensure the integrity and security of the nation.
