在这项工作中，我们提供了第一个二维空间分辨描述MAST-U超级X L模式偏滤器等离子体中的辐射脱离。与传统的排气解决方案相比，Super-X磁结构的设计是为了减少偏滤器靶上的热量和粒子载荷。我们使用过滤相机成像重建二维发射率分布在极向平面的多个原子和分子的发射线和频带。一组氘燃料扫描进行了讨论，在一起，跨度连接到MAST-U中观察到的深分离偏滤器状态。激励剖面便于单独分析刮除层的锁模诱导分裂分支。分子氘Fulcher带发射前沿跟踪表明，氘电子碰撞电离前沿，它作为一个代理，分离在不同的上游电子密度的分裂分支。在分离该电离前沿时，归因于分子活化重组的巴耳末发射出现在目标附近。我们报告的发射腿，与以前的SOLPS-ITER建模一致的同时径向加宽。随着燃料的增加，该发射区分离，这意味着电子温度低于
In this work, we provide the first 2D spatially resolved description of radiative detachment in MAST-U Super-X L-mode divertor plasmas. The Super-X magnetic configuration was designed to achieve reduced heat-and particle loads at the divertor target compared to conventional exhaust solutions. We use filtered camera imaging to reconstruct 2D emissivity profiles in the poloidal plane for multiple atomic and molecular emission lines and bands. A set of deuterium fuelling scans is discussed that, together, span attached to deeply detached divertor states observed in MAST-U. Emissivity profiles facilitate separate analysis of locked-mode induced split branches of the scrape-off layer. Molecular deuterium Fulcher band emission front tracking reveals that the deuterium electron-impact ionisation front, for which it serves a proxy, detaches at different upstream electron densities in the split branches. Upon detachment of this ionisation front, Balmer emission attributed to molecular activated recombination appears near-target. We report a simultaneous radial broadening of the emission leg, consistent with previous SOLPS-ITER modelling. With increased fuelling this emission region detaches, implying electron temperatures below
