使用双重离子束探针对电场和密度进行内部结构测量，以阐明由环形等离子体中高能粒子相互作用驱动的磁流体动力学（MHD）爆发现象的非线性演化。结果对等离子体量的内部结构进行了最精细的观察，例如电场、密度和磁场畸变，这些量在 MHD 现象期间非线性发展。特别是，对于燃烧态等离子体，应强调发现由高能粒子和 MHD 模式之间的相互作用驱动的新型振荡层流。
The internal structural measurements of electric field and density using twin heavy ion beam probes have been performed to elucidate the nonlinear evolution of the magneto-hydro-dynamic (MHD) bursty phenomenon driven by the interaction with high-energy particles in a toroidal plasma. The results have given the finest observation of the internal structure of plasma quantities, such as electric field, density and magnetic field distortion, which nonlinearly develop during the MHD phenomenon. In particular, the finding of a new kind of oscillating zonal flow driven by interaction between energetic particles and MHD modes should be emphasized for burning state plasmas.
