The paper builds the high-current plasma beams model under different dimensions (1D, 2D, and 3D) by continuum (magnetohydrodynamics MHD) and statistical (Monte Carlo MC) mechanics under conditions of low pressures (10 −3 Pa). After detailed presentation of the model, two methods firstly have been analyzed in terms of plasma beam properties. Then, we compare the simulation results of MHD numerical simulation with MC stochastic particles simulation. Finally, through further analysis, it is demonstrated that integrated hybrid MHD and MC method (IMHDMC) provides an innovative practical tool to capture essential properties of high-current plasma beams.

“…In this case, v = ±v 0 where v 0 is the velocity of 3.5 MeV α-particle. For simplicity, the perturbation field has been taken into account only for the first term in the right hand side of (21). The neglected small term could be important for trapped particles since it describes toroidal field ripple due to the perturbation field.…”

On the confinement of passing alpha particles in a tokamak-reactor with resonant magnetic field perturbations shielded by plasma currents

Alpha-particle losses due to the resonant magnetic field perturbations (RMPs) created by the coil system for Edge Localized Mode mitigation in ITER are studied numerically. If shielding of RMPs by the plasma is not taken into account, passing α-particles are the main loss channel which, together with the trapped particle contribution leads to a loss of more than 5 % of fusion alpha particle power. Shielding of RMPs practically eliminates this channel so that the overall losses are reduced to about 1 %.
