Tracking blobs in the turbulent edge plasma of a tokamak fusion device [PDF]

Scientific Reports, 2022
The analysis of turbulence in plasmas is fundamental in fusion research. Despite extensive progress in theoretical modeling in the past 15 years, we still lack a complete and consistent understanding of turbulence in magnetic confinement devices, such as

Neoclassical toroidal plasma viscosity in bounce-transit and drift resonance regimes in tokamaks

Nuclear Fusion, 2023
Neoclassical toroidal plasma viscosity in the bounce-transit and drift resonance regimes is calculated using a version of the drift kinetic equation that encompasses the physics of the nonlinear trapping and quasilinear plateau regimes in tokamaks. It is

First modeling of strongly radiating WEST plasmas with SOLEDGE-EIRENE

Nuclear Materials and Energy, 2019
We present first results of SOLEDGE-EIRENE modeling a strongly radiating plasma in the WEST tokamak. Using measurements from a reciprocating Langmuir probe we have determined the SOLEDGE input parameters, i.e.

Modeling of COMPASS tokamak divertor liquid metal experiments

Nuclear Materials and Energy, 2020
Two small liquid metal targets based on the capillary porous structure were exposed to the divertor plasma of the tokamak COMPASS. The first target was wetted by pure lithium and the second one by a lithium-tin alloy, both releasing mainly lithium atoms (

Modeling snowflake divertors in MAST-U tokamak using UEDGE code

Nuclear Materials and Energy, 2021
In a snowflake (SF) divertor, two magnetic field nulls are placed close to each other creating four strike points (SPs) cf. two in a standard single-null (SN) divertor.

Testing of the SOLPS-ITER code at Globus-M2 spherical tokamak with detached divertor

MATEC Web of Conferences, 2018
In according to a present understanding of Scrape-Off Layer (SOL) physics, future thermonuclear devices like ITER, DEMO and beyond, require high radiation regimes in order to reduce heat loads on tokamak divertor. Recent experiments at ASDEX Upgrade, JET
