在Heliotron J装置上成功地将超声分子束注入（SMBI）气体燃料应用于ECH/NBI等离子体中。（0.35兆瓦）和NBI（约0.6 MW），这比Heliotron J中的常规喷气下迄今为止实现的最大值高约50%。在ECH+NBI等离子体的SMBI脉冲之后，在中心和外围区域中同时引起辐射分布中的两种不同类型的扰动。对于ECH等离子体，SMBI脉冲引起电子温度的增加或降低，这似乎取决于靶密度（© 2010 WILEY-VCH Verlag GmbH & Co. KGaA，魏因海姆）
Gas fueling by supersonic molecular beam injection (SMBI) is successfully applied to ECH/NBI plasmas in Heliotron J. The stored energy reached ∼4.5 kJ for a heating combination of ECH (∼0.35 MW) and NBI (∼0.6 MW), which is about 50 % higher than the maximum one achieved so far under the conventional gas‐puffing in Heliotron J. After an SMBI pulse for ECH+NBI plasma, two different kinds of perturbation in the radiation profile are caused simultaneously in the center and the peripheral regions. For ECH plasma, an SMBI pulse causes increase or decrease of electron temperature, which seems to depend on the target density (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
