An approach to explore the eddy currents of the new type divertor for EAST device using ANSYS code [PDF]

, 2016
An effective method for eddy current calculation has been developed for EAST’s new divertor by using ANSYS. A 3D model of a double null divertor for the EAST device was built to evaluate eddy currents and electromagnetic (EM) forces on these components ...

Divertor tungsten source monitoring by A visible spectroscopy diagnostic on EAST

Nuclear Materials and Energy
EAST has been upgraded with top and bottom tungsten divertors to facilitate the high power long pulse operation. A visible spectroscopy diagnostic has been developed progressively to monitor W source as well as line emissions from other particles (e.g ...

Plasma pressure and particle loss studies in the Pilot-PSI high flux linear plasma generator

Nuclear Materials and Energy, 2017
Plasma detachment in tokamak divertors reduces the particle and power fluxes to the plasma facing components and is essential for successful operation of ITER. The linear plasma generator Pilot-PSI can produce a high density (∼1021 m−3), low temperature (

Kinetic and hydrodynamic regimes in multi-particle-collision dynamics of a one-dimensional fluid with thermal walls

Physical Review Research, 2021
We study the nonequilibrium steady states of a one-dimensional fluid in a finite-space region of length L. Particles interact among themselves by multi-particle collisions and are in contact with two thermal-wall heat reservoirs, located at the ...

Fuel recycling control in long pulse operation with full tungsten divertors in EAST tokamak

Nuclear Materials and Energy, 2023
Fuel recycling control in long pulse discharges is studied in EAST tokamak with tungsten divertors by particle balance. Double null configuration, proper Resonant Magnetic Perturbation (RMP), divertor cryopumps and realtime lithium injection, are all ...

Formation of convective cells in the scrape-off layer of the CASTOR tokamak [PDF]

, 2004
Understanding of the scrape-off layer (SOL) physics in tokamaks requires diagnostics with sufficient temporal and spatial resolution. This contribution describes results of experiments performed in the SOL of the CASTOR tokamak (R=40 cm, a = 6 cm) by ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

HEAT simulation and IR data comparison for ST40 plasma-facing components

Nuclear Materials and Energy
The Heat Flux Engineering Analysis Toolkit (HEAT) (Looby et al., 2022) was used to simulate the heat flux, qtarget, on ST40 molybdenum divertors. Results were compared with experimental infrared (IR) data.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

SOLPS-ITER numerical simulations of ITER-scale Snowflake divertors: low-field-side SF−/SF+ and high-field-side SF−/SF+ configurations

Nuclear Fusion
Using the edge plasma code package SOLPS-ITER, we study the four types of Snowflake (SF) divertors for an ITER-size tokamak, with toroidal magnetic field B _T ∼ 5 T, major radius R ∼ 5 m and plasma current I _p ∼ 10 MA.
