In support of the ICRF experiments planned on the Wendelstein 7-X (W7-X) stellarator, i.e. fast ion generation, wall conditioning, target plasma production and heating, a first experimental study on plasma production has been made in the Uragan-2M (U-2M) stellarator using W7-X-like two-strap antenna. In all the experiments, antenna monopole phasing was used. The W7-X-like antenna operation with launched radiofrequency power of ~100 kW have been performed in helium (p = (4–14) × 10−2 Pa) with the vacuum vessel walls pre-loaded with hydrogen. Production of plasma with a density higher than 1012 cm−3 was observed near the first harmonic of the hydrogen cyclotron frequency. Operation at first hydrogen harmonic is feasible in W7-X future ICRF experiments.

为了支持计划在Wendelstein 7-X（W7-X）恒星仪上进行的ICRF实验（即快速离子产生，壁调节，目标等离子体产生和加热），已在Uragan-2M中进行了等离子体产生的第一项实验研究（ U-2M）恒星器，使用类似W7-X的两带天线。在所有实验中，均使用天线单极定相。已在氦气中（p  =（4-14）×10 -2 Pa）在真空容器壁中预装了氢气的情况下，发射了约100 kW的射频功率，类似W7-X的天线运行。产生密度高于10 12 cm -3的等离子体在氢回旋加速器频率的一次谐波附近观察到。在W7-X未来的ICRF实验中，第一次氢谐波操作是可行的。
