一个旋转场天线组-一对两个紧密间隔的双半圈天线-用于定制天线场的方位角频谱。结果表明，ICRF波的方位模式可以通过天线组的适当定相来控制。离子加热示出强烈依赖于方位角模式数。当天线组在m =-1（左旋转）模式下操作时，m =-1修改的离子回旋波被选择性地激发，导致有效的离子加热。
A rotating field antenna set — a pair of two closely spaced dual half-turn antennas — is used to tailor the azimuthal spectrum of the antenna field. It is demonstrated that the azimuthal mode of ICRF waves can be controlled by proper phasing of the antenna set. Ion heating is shown to be strongly dependent on the azimuthal mode number. When the antenna set is operated in the m = −1 (left rotating) mode, the m = −1 modified ion cyclotron wave is selectively excited, resulting in efficient ion heating.
