Abstract:

A simulation code is used to simulate the whole tokamak discharge process for parameters relevant to EAST. This simulation takes into account of the plasma bootstrap current, ion cyclotron resonance heating and fast wave current drive. A D-shape plasma equilibrium with peak density of 1.2×10²⁰m^-3, T_e=4.5keV, T_i=3.8keV is got. According to the simulation results, we make a analysis of flux consumption for EAST, and study influences of the plasma current ramp up time and the effective charge.

Key words: bootstrap current, ICRH, FWCD, Flux consumption

摘要：

用TSC程序模拟了EAST装置等离子体放电的全过程。模拟中考虑了自举电流，并加入了离子回旋共振加热ICRH和快波电流驱动FWCD，得到了中心电子温度4.5keV、中心离子温度3.8keV、中心电子密度1.2×10²⁰m^–3的D形截面的等离子体。根据模拟结果对EAST装置进行了伏秒数分析，并研究了不同等离子体电流上升时间、有效电荷数Z_eff对放电的影响。
