提出了一种用于大型托卡马克的新型脊波导开槽耦合器，并通过实验指出了其良好的特性。连接在脊状波导末端的一个短路和覆盖其口的一系列狭槽，以与主环形磁场正交的电场向等离子体发射离子回旋频率范围（ICRF）波。用水代替等离子体负载的模拟实验表明，当与水的距离为0.02¿0和0.04¿0时，典型波导的电压驻波比分别为3.0和5.0。插入耦合器的匹配部分将其驻波比降低到三分之一以下。
A new ridged waveguide slotted coupler is proposed for large tokamaks and its promising characteristics are pointed out experimentally. A short circuit attached to the end of a ridged waveguide and a series of slots to cover the mouth launch the ion-cyclotron range of frequencies (ICRF) waves into the plasma with electric field orthogonal to the main toroidal magnetic field. The simulated experiment using water instead of the plasma load showed that the voltage standing-wave ratio (VSWR) in one typical guide is 3.0 and 5.0 for the distance to water being 0.02 ¿0 and 0.04 ¿0, respectively. The matching section inserted into the coupler reduces its VSWR to less than one-third.
