Tailoring steep density profile with unstable points
Shun Ogawa, Xavier Leoncini, Alexei Vasiliev +1
The mesoscopic properties of a plasma in a cylindrical magnetic field are investigated from the view point of test-particle dynamics. When the system has enough time and spatial sy…
Study on creation and destruction of transport barriers via effective safety factors for energetic particles
Shun Ogawa, Xavier Leoncini, Guilhem Dif-Pradalier +1
Charged particles with low kinetic energy move along magnetic field lines, but so do not energetic particles. We investigate the topological structure changes in the phase space of…
Full particle orbit effects in regular and stochastic magnetic fields
Shun Ogawa, Benjamin Cambon, Xavier Leoncini +4
We present a numerical study of charged particle motion in a time-independent magnetic field in cylindrical geometry. The magnetic field model consists of an unperturbed reversed-s…
