Electromagnetic hot plasma waves near electron cyclotron frequency: a possibility of anomalous electron heating

K Matsuda1986年Plasma Physics and Controlled FusionIF 2.2出版社

In the electromagnetic hot plasma dispersion equation, there are a number of heavily damped modes. Among them, a few branches in the frequency range 0.8< omega / Omega <1, where Omega is the electron cyclotron frequency, may still propagate. If a launched electromagnetic wave excites these modes, it results in an anomalous heating. The energy deposition of this mechanism is not inconsistent with the electron cyclotron heating experiment of overdense plasmas in Doublet III.

電磁波の高温プラズマ分散方程式には、多数の強く減衰するモードが存在する。その中で、周波数範囲 0.8 < ω / Ω < 1(ここで Ω は電子サイクロトロン周波数)におけるいくつかの分枝は、依然として伝播し得る。入射された電磁波がこれらのモードを励起すると、異常加熱が生じる。この機構によるエネルギー沈着は、ダブレットIIIにおける過密プラズマの電子サイクロトロン加熱実験と矛盾しない。
