First operation of a dedicated runaway electron mitigation coil (REMC)

Nuclear Fusion
We 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.

Phase Diagrams Enable Solid‐State Battery Design

Advanced Materials Interfaces, EarlyView.
Batteries are non‐equilibrium devices with inherent thermodynamic driving forces to react at interfaces, regardless of kinetics or operating conditions. Chemical potential mismatches across interfaces are dissipated via interfacial reactions. In this work, it is illustrated how phase diagrams and chemical potential maps predict degradation pathways but

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 ...

Comparison of start-up runaway electron generation simulations using the SCENPLINT code with JET experimental observations

Nuclear Fusion
This paper explores the process of runaway electron (RE) formation during the start-up of a tokamak discharge. This has been done by simulating the process of RE generation and, importantly their losses, self-consistently with the behavior of many other ...
