The article presents an analysis of the typical features of shear Alfvén waves in tokamak plasmas in a frequency domain ranging from the `high' frequencies (ω ≅ vA/2qR0, where vA is the Alfvén speed and qR0 is the tokamak connection length) of thetoroidal gap to the `low' frequencies, comparable with the thermal ion diamagnetic frequency ω*pi and/or the thermal ion transit frequency ωti = vti/qR0 (where vti is the ion thermal speed).

本稿では、トカマクプラズマにおけるシア・アルフヴェン波の典型的な特徴について、トロイダルギャップの「高」周波数(ω ≅ vA/2qR0、ここでvAはアルフヴェン速度、qR0はトカマクの結合長)から、熱的イオンの反磁性周波数ω*piおよび/または熱的イオンの通過周波数ωti = vti/qR0(ここでvtiはイオンの熱速度)に匹敵する「低」周波数に至る周波数領域にわたって解析を行ったものである。
