HT－6M装置上离子回旋波的传播和吸收

THEORETICAL STUDY OF PROPAGATION AND ABSORPTION OF ICRF WAVE IN THE HT-6M TOKAMAK

本文从波与粒子相互作用的线性理论出发，结合ＨＴ－６Ｍ托卡马克少数离子为氢，基本离子为氘［Ｈ（Ｄ）］的等离子体离子回旋共振加热（ＩＣＲＨ）为例，讨论了离子回旋波在这特定的等离子体中传播、吸收与少数离子氢的浓度ＲＨ（定义为ｎＨ／ｎｅ，ｎＨ为氢离子密度，ｎｅ是等离子体总密度）和平行波数ｋ‖的关系。文中最后还给出了ＨＴ－６Ｍ托卡马克离子回旋共振加热的优化实验方案。

A linear theory of minority ion ICRF heating in H/D plasma of HL-6M tokamak is presented.The results from an accurate numerical calculation combined with brief analysis demonstrate the physical relation of propagation,or damping absorption,of ICRE wave to two important parameters, the minority ion concentration RH(=nH/ne,including RH=0)and the wave number k. Finally an optimum option for ICRH in the HL-6M tokamak is proposed.
