Global 3D full-scale turbulence simulations of TCV-X21 experiments with SOLEDGE3X

Nuclear Materials and Energy
First principle modelling of edge plasma turbulence including neutrals and plasma recycling on the wall remains a challenge, in particular due to the long time scales necessary to simulate to reach particle balance.

Plasma flow generation and particle acceleration from expanding magnetic bubbles

Physical Review Research
Impulsive plasma dynamics in the laboratory are often driven by rising electric currents, yet their quantitative plasma response has not been well established.

Development of the Langmuir probe under q-distribution for NCST

AIP Advances
The Langmuir probe is one of the important diagnostic methods for measuring the edge plasma parameters of tokamak. A quadruple Langmuir probe (QLP) system was designed and built on the NanChang Spherical tokamak (NCST).

Autoregressive long-horizon prediction of plasma edge dynamics

Nuclear Fusion
Accurate modeling of scrape-off layer (SOL) and divertor-edge dynamics is vital for designing plasma-facing components in fusion devices. High-fidelity edge fluid/neutral codes such as SOLPS-ITER capture SOL physics with high accuracy, but their ...

Observation of plasma performance improvement by edge ECRH power deposition on Experimental Advanced Superconducting Tokamak

Nuclear Fusion
Edge electron cyclotron current drive (ECCD) has been observed to enhance plasma performance on the Experimental Advanced Superconducting Tokamak. By adjusting the ECCD mirror, the power deposition was shifted from the core to the edge region during H ...

Tailoring tokamak error fields to control plasma instabilities and transport

Nature Communications
A tokamak relies on the axisymmetric magnetic fields to confine fusion plasmas and aims to deliver sustainable and clean energy. However, misalignments arise inevitably in the tokamak construction, leading to small asymmetries in the magnetic field known

Quantum Hall edges beyond the plasma analogy

Physical Review Research
We demonstrate that the widely used plasma analogy is unreliable at predicting edge properties of quantum Hall states. This discrepancy arises from a fundamental difference between quantum Hall droplets and plasmas (Coulomb gases): The former are ...

Influence of the safety factor variation on exitation of resonant magnetic perturbation in TOKAMAK rotating edge plasmas

East European Journal of Physics, 2013
Recently the possibility of resonant excitation of pressure perturbation by external helical magnetic perturbations near the rotating plasma edge was shown taking into consideration the finite plasma conductivity.
