Assessment of runaway electron beam termination and impact in ITER
Nuclear FusionThe 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

Advanced Materials Technologies, EarlyView.An in situ electroplating approach for MEX 3D printing is proposed, enabling copper deposition during the fabrication of conductive polymers. The method combines a printer‐integrated plating head, ML‐based g‐code control, and stop‐and‐go printing, achieving near‐bulk copper conductivity and enabling fully embedded, assembly‐free electronic components ...

First operation of a dedicated runaway electron mitigation coil (REMC)
Nuclear FusionWe report observations from the first experimental tests of a dedicated runaway electron mitigation coil (REMC) installed inside a tokamak’s vacuum vessel and driven by the disruption loop voltage.

Modeling of runaway electron induced damage on boron-nitride tiles in WEST
Nuclear Materials and EnergyThe runaway electron (RE) - induced damage on boron nitride (BN) tiles mounted on the inner bumpers of the WEST tokamak is modeled employing available empirical input and experimental constraints, concerning the post-mortem documentation of the damaged ...

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

Advanced Materials Technologies, EarlyView.Anodic aluminum oxide (AAO) membranes have traditionally served as structural supports in osmotic energy systems. Here, blind‐hole AAO membranes are demonstrated as active ion‐selective platforms with tunable nanopore structures. By balancing membrane resistance, ion selectivity, and flux, enhanced performance is achieved, delivering a maximum power ...

Magnetohydrodynamic instability modulated runaway electron losses in the ADITYA-U tokamak
Nuclear FusionIn the ADITYA-U tokamak, modulation in the Hard x-ray (HXR) emission from the limiter synchronous with a m/n = 2/1 tearing mode is observed during the flat-top and pre-disruption phases of a discharge with a significant runaway electron (RE) population ...

Advanced Robotics Research, EarlyView.Amphiphilic chloroazobenzenes, bearing different amino acids as end groups alanine, phenylalanine, and valine, exhibit excellent photoisomerizations. Varying structures of three amino acid groups participate in supramolecular formations and therefore photoinduced morphological transformations via adjusting intermolecular interactions. These interaction
