Abstract

During this research internship we want to study the magnetic field topology in tokamaks subjected to Resonant Magnetic Perturbations (RMPs) in contact with the theoretical and experimental groups of DIII-D at the General Atomics. For this we will use the methods developed during the doctoral research to describe the hydromagnetic equilibrium of shaped plasmas with single or double null separatrix at the DIII-D tokamak. Then we will include the vacuum RMPs that describe the magnetic field created by the correction coils (C-coils) of the machine. Further, the plasma response will be included as an additional field created by asymmetric current distributions inside the plasma. The modeling of these currents will rely on the magnetic structures created by the vacuum RMPs and the plasma equilibrium profiles. Then, the effect of the plasmas response on the magnetic topology will be compared to the vacuum perturbation case where the plasma current density is considered axisymmetric and both will be confronted with the available experimental results from the DIII-D team.
