Collisionless absorption in sharp-edged plasmas
Physical Review Letters, 1992 The absorption of subpicosecond, obliquely incident laser light is studied using a 11/2D particle-in-cell code. Density scale lengths from L/\ensuremath{\lambda}=0.01 to 2 and laser irradiances between I${\ensuremath{\lambda}}^{2}$=${10}^{14}$ and ${10}^{18}$ W ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}2}$ \ensuremath{\mu}${\mathrm{m}}^{2}$ are considered.

Effect of aspect ratio on plasma response to resonant magnetic perturbations in tokamak devices
AIP Advances, 2023 A systematic numerical study is carried out, computing and comparing the plasma response to the resonant magnetic perturbation (RMP) field, applied for controlling edge localized modes (ELMs), in a series of tokamak plasmas with varying aspect ratio and ...

Boundary Reconstruction of Tokamak Plasma Based on Deep Neural Networks
南方能源建设, 2022 [Introduction] In order to realize the real-time reconstruction of plasma shape and position in tokamak, a visible light edge reconstruction algorithm based on fully connected neural network is proposed based on the analysis of camera calibration ...

Exploration of non-resonant divertor features on the Compact Toroidal Hybrid
Nuclear Fusion, 2023 Non-resonant divertors (NRDs) separate the confined plasma from the surrounding plasma facing components (PFCs). The resulting striking field line intersection pattern on these PFCs is insensitive to plasma equilibrium effects.

Chaos in 1D Radiative Edge Plasmas [PDF]
Contributions to Plasma Physics, 2002 Bifurcation and chaos in radiative edge plasmas are investigated on the basis of a periodically driven reaction-diffusion equation which results from the time dependent 1d heat conduction equation including a given periodically time-modulated impurity density. The temporal problem shows the transition to chaos through the Feigenbaum route.

Effect of local wall clearance on scrape-off layer electron density profiles in ASDEX Upgrade
Nuclear FusionThe plasma electron density is measured with multiple diagnostics in the scrape-off layer of the ASDEX Upgrade tokamak. The recorded values are typically in good agreement in the case of exponentially decaying profiles at low densities, but they become ...
