Kinetic simulation of Alfv\'{e}nic instabilities in tokamaks

Toroidicity induced Alfv\'{e}n eigenmode in a tokamak geometry is studied by numerical simulation including both the high energy particles and bulk kinetic plasmas. To see the interaction between the high energy and the bulk (incorporate ions and electrons to statistically reliable level), effective parallelization is the key. Computational procedure of the simulation is discussed.
