Assessment of runaway electron beam termination and impact in ITER

Nuclear Fusion
The vertical motion and shrinking of the cold plasma column after a tokamak disruption leads to a natural decrease in the edge safety factor when most of the current is carried by runaway electrons (REs). Reaching a low edge safety factor can potentially

Experimental study of m/n=2/1 mode RMP on the runaway current suppression during disruptions on J-TEXT

Nuclear Fusion
A systematic experimental study of m / n = 2/1 mode resonant magnetic perturbation (RMP) on the runaway current suppression is carried out on J-TEXT. The RMP is applied before disruptions which are deliberately triggered by massive gas injection (MGI ...

Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

Advanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...

Is the guiding-center radiation model applicable to runaway electron dynamics?

Nuclear Fusion
For energetic runaway electrons in tokamaks, synchrotron radiation is the main mechanism of energy loss and an important means for diagnosis. It has been revealed that the lowest order guiding-center assumption no longer holds for energetic runaway ...
