HT-6M中性束注入加热理论分析

THEORETICAL STUDY FOR NEUTRON BEAM INJECTION HEATING

通过数值求解含时、二维(速度空间)、非线性的Fokker-Planck方程,计算了HT-6M托克马克在中性束注入加热条件下的离子温度、分布函数随时间的演化.随着中性束的注入,离子温度稳步增加,分布函数出现高能平台和非同向分布,计算结果和现有的实验符合较好.

The neutron beam injection (NBI) heating exeriment on HT-6M Tokamak was studied with the two-dimension (in velocity space), time-dependent, non-linear and multispecies Fokker-Planck Equation. The temporal evolution of ion distribution function and relevant parameters were calculated and compared with experimental data. The calculation shows that the ion temperature increases, high energy platform (5-10keV) and anisotropy appear when the neutron beam was injected into plasma, which shows satisfactory agreement with avialable experimental data.
