Le CEA est un acteur majeur de la recherche, au service des citoyens, de l'économie et de l'Etat.
Il apporte des solutions concrètes à leurs besoins dans quatre domaines principaux : transition énergétique, transition numérique, technologies pour la médecine du futur, défense et sécurité sur un socle de recherche fondamentale. Le CEA s'engage depuis plus de 75 ans au service de la souveraineté scientifique, technologique et industrielle de la France et de l'Europe pour un présent et un avenir mieux maîtrisés et plus sûrs.
Implanté au coeur des territoires équipés de très grandes infrastructures de recherche, le CEA dispose d'un large éventail de partenaires académiques et industriels en France, en Europe et à l'international.
Les 20 000 collaboratrices et collaborateurs du CEA partagent trois valeurs fondamentales :
- La conscience des responsabilités
- La coopération
- La curiosité
Fusion energy is one of the promising solutions to create a carbon neutral civilization. To achieve this goal before the end of this century, the ITER project (www.iter.org), started at Cadarache in 2005, should demonstrate in the next decades the technical feasibility of controlled fusion reactions into a facility called a tokamak. To prepare ITER startup and operation, the WEST (Tungsten (W) Environment in Steady-state Tokamak) project (built from the former Tore Supra tokamak) aims at testing plasma facing components and long-duration pulse operation in a fully metallic environment.
To control the plasma of WEST, several feedback controls are required. One of them is the density control : a real-time measurement of the integrated plasma density along a line-of-sight is used to inject more or less gas into the vacuum vessel in order to match the desired density. Recently, in collaboration with the Dutch Institute for Fundamental Energy Research, the real-time plasma density reconstruction code RAPDENS has been adapted to the WEST Plasma Control System (PCS). IT will provide a full profile of the density from the plasma center to the edge in real time. With these new values for the PCS, new density controllers based on plasma central density, for example, could BE developed and tested, improving the operation domain of WEST.
The student will finalize the real-time implementation of the considered reconstruction code into the WEST PCS. Then, he/she will assess the results and adjust the different parameters of the code. This work will bring the student to develop post-analysis scripts to analyze the generated data. Then he/she could improve the code in order to increase its flexibility and its robustness. Finally, a user guide should BE written in order to keep the knowledge available for the WEST team.
