Development of a dispersion strengthened copper alloy using a MA-HIP method

Nuclear Materials and Energy, 2016
A new Cu-Al alloy was fabricated by a MA-HIP method for application to the heat sink materials of divertors. With the increase in MA time, the grain size and Vickers hardness decreased and increased, respectively. At MA time of 32hrs, the hardness of the

Photoconductivity‐Driven Quantum Efficiency Gain in Inorganic Ruddlesden‐Popper Layered Cs2PbBr2I2 Perovskite Photodetector for Visible Light Detection

Advanced Functional Materials, EarlyView.
Rational halogen mixing strategy was employed to shift the bandgap of Cs2PbBr2I2 from ultraviolet to visible region, enabling first realization of a visible‐light photodetector with this 2D layered Ruddlesden‐Popper perovskite material. Under illumination, light‐induced internal field forms and drives trap‐mediated persistent photoconductivity ...

The topology of non-resonant stellarator divertors

Nuclear Fusion
We apply topological methods to better understand how the magnetic field in the stellarator edge can be diverted away from the confined region. Our primary method is calculating the winding numbers of closed contours, which gives information on the ...

Multiscale particle simulation of the temporal evolution of heat flux into poloidal gaps of castellated divertor with edge-localized modes

Nuclear Fusion, 2023
Edge-localized modes (ELMs) produce an intense transient heat flux on castellated divertor mono-blocks (MBs). The parallel transport of electrons and ions from the ELM burst varies due to their different velocities, which significantly influences the ...

Towards radiation transport modelling in divertors with the EIRENE code [PDF]

, 2001
Opacity effects, in particular of Lyman lines, in divertors are believed to be relevant for plasma spectroscopy and for the overall divertor dynamics through possible redistribution of excited hydrogen atoms and radiation losses.

Characterizing impurity sourcing and transport in the high temperature boundary of DIII-D wide pedestal QH-mode plasmas

Nuclear Fusion
Wide Pedestal QH-mode (WPQH) plasmas in the DIII-D tokamak show a sheath limited SOL, where electron density and temperature remain nearly constant along field lines from the midplane to the divertor. Consequently, parallel gradients are weak.
