Energetic particles transport in constants of motion space due to collisions in tokamak plasmas
Guo Meng, Philipp Lauber, Zhixin Lu +2
The spatio-temporal evolution of the energetic particles in the transport time scale in tokamak plasmas is a key issue of the plasmas confinement, especially in burning plasmas. In…
