An innovative approach is proposed for the protection of plasma-facing surface of blankets (solid first wall), which will also serve as an automatic disruption mitigation system. In a strong magnetic field, liquid metal is frozen in the magnetic field. This property enables liquid metal to flow along the field line. In a divertor configuration with a lower single-null, a second separatrix exists above the plasma. Toroidally-continuous liquid metal sheets, poured through a toroidal slot located radially outside the 2nd separatrix flux surface, move along the field line, absorbing heat and particles, reach the divertor at a glancing angle. At the current quench in a disruption, a toroidal current is induced automatically in the liquid metal surrounding the core plasma. The resultant j × B force pushes the liquid metal toward the core plasma, significantly mitigating the heat load and force on the first wall and the divertor. Use of magnetically-guided liquid metal FW would also eliminate the need of fine shaping and toroidal alignment of the first wall.

磁导液态金属第一壁 (MAGLIMFW)，内置自动中断缓解系统

提出了一种创新方法来保护面向等离子体的毯子表面（固体第一壁），它也将用作自动中断缓解系统。在强磁场中，液态金属在磁场中冻结。这种特性使液态金属能够沿磁力线流动。在具有较低单零值的偏滤器配置中，等离子体上方存在第二个分离线。环形连续液态金属板，通过位于第二个分离面通量表面径向外侧的环形槽浇注，沿场线移动，吸收热量和颗粒，以掠射角到达偏滤器。在中断中的电流失超时，会在核心等离子体周围的液态金属中自动感应出环形电流。合成的 j × B 力将液态金属推向核心等离子体，显着减轻第一壁和偏滤器上的热负荷和力。磁导液态金属 FW 的使用也将消除对第一壁的精细成形和环形对准的需要。
