首次研究了平面偏振m=/spl plusmn/1和m=/spl plusmn/2模式螺旋波产生等离子体的特性。平面极化m=/spl plusmn/1和m=/spl plusmn/2模式螺旋波主要分别使用名古屋III型天线和四极天线来激发。对热电子引起的 ArII 光发射进行了二维交叉场测量，以研究射频功率沉积。将用磁探针测量的波磁场分量与 m=/spl plusmn/1 和 m=/spl plusmn/2 模式计算的场分布进行比较。对于 m=/spl plusmn/1 和 m=/spl plusmn/2 模式，分别观察到两个和四个高强度等离子体柱。这些柱位于天线腿之间的区域。波磁场的径向分布与计算结果吻合良好。
The characteristics of plasma produced by plane polarized m=/spl plusmn/1 and m=/spl plusmn/2 mode helicon waves were investigated for the first time. Plane polarized m=/spl plusmn/1 and m=/spl plusmn/2 mode helicon waves were mainly excited using a Nagoya type III antenna and a quadrupole antenna, respectively. Two-dimensional cross-field measurements of ArII optical emission induced by hot electrons were made to investigate the RF power deposition. The components of the wave magnetic field measured with a magnetic probe were compared with the field profiles computed for the m=/spl plusmn/1 and m=/spl plusmn/2 modes. Two and four high intensity plasma columns were observed for the m=/spl plusmn/1 and m=/spl plusmn/2modes, respectively. These columns were located at the regions between the antenna legs. The radial profiles of the wave magnetic field were in good agreement with computations.
