Location: Ecole Polytechnique Fédérale de Lausanne (map)

Room: CO 260


Course book of the doctoral school at EPFL

Fusenet: The European Fusion Education Network

Prerequisite: it is advantageous to have a basic (undergraduate) knowledge of signal processing and control theory.

The course lasts one week (2 ECTS) and is open to EPFL students and also students from other Universities and Institutes, including FUSENET members. In this course, Ph.D. and Master Students will become familiar with the key issues in plasma control and operations. They will become acquainted with techniques for modeling the dynamical behavior of tokamaks and for design of control algorithms. During the course, students will do exercises using discharge preparation programs, equilibrium reconstruction codes, and control-oriented plasma models used in the tokamak community, in particular on the TCV tokamak.
