The influence of magnetic islands on the impurity ion motion in the drift optimized stellarator
The motion of the charged test particles ensemble of tungsten ions in the drift optimized stellarator Wendelstein 7-X with the chain of 5 magnetic islands is studied. The numerical code solves the guiding center equations written in the Hamiltonian form. To simulate the Coulomb scattering the Mont...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The motion of the charged test particles ensemble of tungsten ions in the drift optimized stellarator Wendelstein
7-X with the chain of 5 magnetic islands is studied. The numerical code solves the guiding center equations written
in the Hamiltonian form. To simulate the Coulomb scattering the Monte Carlo collision operator is used. The scattering
of the particles due to the collisions and magnetic islands is shown. The question of the possibility to use the
magnetic islands for the prevention of impurity penetration to the plasma is discussed |
