The role of the electron-collecting disc in the excitation of electrostatic ion-cyclotron waves

P H Krumm, M J Alport1984年Plasma Physics and Controlled FusionIF 2.2出版社

Current driven electrostatic ion-cyclotron waves are excited by drawing a current to an electron-collecting disc (button) in a Q-machine. They are detected in the noise spectrum of the button, the hot plate emission current, and of a probe located at the mid-region of the plasma. By changing the magnetic field locally, the authors show that electrostatic ion-cyclotron waves are excited at frequencies determined by the local button field and the main field of the plasma.

Qマシンにおいて、電子捕集円板(ボタン)に電流を引き込むことによって、電流駆動の静電イオンサイクロトロン波が励起される。それらは、ボタンの雑音スペクトル、熱板の放出電流、およびプラズマの中央領域に配置されたプローブの雑音スペクトルにおいて検出される。磁場を局所的に変化させることによって、著者らは、静電イオンサイクロトロン波が、局所的なボタン磁場とプラズマの主磁場によって決定される周波数で励起されることを示している。
