CFETR稳态运行模式的0.5维集成模拟及其杂质粒子比例影响的分析

1/2 dimensional integrated simulation of CFETR steady state operation scenario and analysis of the impact of impurity particle ratio

采用快速集成模拟软件METIS完成了CFETR1GW稳态反剪切运行模式的设计。该反剪切运行模式由40MW离轴电子回旋电流驱动(ECCD)与60MW的离轴中性束电流驱动(NBCD)所实现,获得了稳定的安全因子剖面,其在ρ=0.52处具有最小安全因子q_(min)=3.1,从而可避免危险的m/n=2/1、3/2、5/3的新经典撕裂模(NTM)。此外,本文还分析了Ar杂质粒子的含量对此稳态反剪切模式约束性能的影响。

A 1GW fusion power reversed shear(RS) scenario is designed for CFETR steady state operation using the fast integrated modelling tool,METIS.This RS scenario is maintained by 40MW off-axis electron cyclotron current driving(ECCD) and 40 MW neutral beam current driving(NBCD).In this scenario,the steady safety factor profile has a minimal q,q_(min)=3.1 at ρ=0.52.Therefore,the dangerous m/n=3/2,2/1,5/3 NTM(neoclassical tearing mode) would be avoid.The influence of Argon atom fraction in plasma on the performance of this RS scenario is also analyzed.
