给出了离子回旋频段内冷等离子体和热等离子体介电张量表达式,计算得到了其分布,并进行了对比。结果表明:热等离子体更能反映托卡马克等离子体的介电性质,在托卡马克离子回旋波电流驱动的相关研究中应尽量采用热等离子体模型。
The expression of the dielectric tensors both in cold and hot plasmas is given in the ion cyclotron range.Dielectric tensors in cold and hot plasmas are calculated,also results are compared.It shows that the dielectric tensor in hot plasmas supposition is more reasonable,so the hot plasmas dielectric should be adopted in study of ion cyclotron current drive in Tokamak.
