在DIII-D托卡马克中，在氖气和氩气雾化的情况下，观察到杂质诱导的辐射功率分数（Prad/Pin）从50%到100%的增强能量约束。这些辐射地幔增强约束放电在DIII-D托卡马克中已在多种条件下获得：具有h模和l模边缘的转移和有限配置。尽管在最高密度下的操作是短暂的，但通过杂质气体膨化获得的约束增强达到了ELM自由h模标度关系。讨论了在TEXTOR托卡马克中获得的DIII-D模式放电与ri模式放电的异同。
Enhanced energy confinement in discharges with impurity induced radiating power fractions, Prad/Pin, from 50% to 100% have been observed in the DIII-D tokamak with neon and argon gas puffing. These radiating mantle enhanced confinement discharges have been obtained in the DIII-D tokamak under a variety of conditions: diverted and limited configurations with both an H-mode and L-mode edge. Confinement enhancements as high as the ELM free H-mode scaling relation have been obtained with impurity gas puffing, although operation at the highest densities is transient. Similarities and differences between these DIII-D discharges and RI-mode discharges obtained in the TEXTOR tokamak are discussed.
