Gyrokinetic Simulation of Tokamak Edge Plasmas
It has been recently discovered that the trapped electron mode (TEM) may play an important role in the H mode edge plasma for domestic tokamaks such as EAST and HL-2A. The stability and transport for TEM for the edge parameters are studied using large scale gyrokinetic particle simulations. The gyrokinetic simulation reveals the parametric dependences on the wavelength and collisionality. The b...
متن کاملGlobal gyrokinetic simulation of Tokamak edge pedestal instabilities.
Global electromagnetic gyrokinetic simulations show the existence of near threshold conditions for both a high-n kinetic ballooning mode (KBM) and an intermediate-n kinetic version of peeling-ballooning mode (KPBM) in the edge pedestal of two DIII-D H-mode discharges. When the magnetic shear is reduced in a narrow region of steep pressure gradient, the KPBM is significantly stabilized, while th...
متن کاملToward a first-principles integrated simulation of tokamak edge plasmas
Performance of the ITER is anticipated to be highly sensitive to the edge plasma condition. The edge pedestal in ITER needs to be predicted from an integrated simulation of the necessary firstprinciples, multi-scale physics codes. The mission of the SciDAC Fusion Simulation Project (FSP) Prototype Center for Plasma Edge Simulation (CPES) is to deliver such a code integration framework by (1) bu...
متن کاملSimulation of Power Exhaust in Edge and Divertor of the SlimCS Tokamak Demo Reactor
Design of the power handling for the demo tokamak reactor, SlimCS, with the fusion power of Pfus ≤ 3 GW and the exhausted power of Pout = 500 MW was investigated. First, effects of the divertor geometry of the V-shaped corner and the Ar impurity seeding on the radiation distribution and the target power loading were summarized in the simulation (SOLDOR/NEUT2D) with a constant concentration of A...
