Implementation of a High-Speed Multichannel Data Acquisition System for Magnetic Diagnostics and Plasma Centroid Position Control in ISTTOK

open access: yesIEEE Access, 2023
In tokamak and other fusion devices, magnetic control is the main tool that allows to regulate the plasma current, position and shape; it is in charge of actuating the desired plasma current waveform, steering the plasma position to a given set point and

Surface Problems of Tokamak Devices

open access: yesHyomen Kagaku, 1982
Surface problems encountered during plasma confinement experiments in tokamak devices are described in the following context : causes of impurity introduction into the plasma, control of impurity release, fuel recycling, testing of first wall material, and a problem related to additional heating.

Transport of dust particles in tokamak devices [PDF]

open access: yesJournal of Nuclear Materials, 2007
Recent advances in the dust transport modeling in tokamak devices are discussed. Topics include: (1) physical model for dust transport; (2) modeling results on dynamics of dust particles in plasma; (3) conditions necessary for particle growth in plasma; (4) dust spreading over the tokamak; (5) density profiles for dust particles and impurity atoms ...

Distinct turbulence saturation regimes in stellarators [PDF]

open access: yes, 2017
In the complex 3D magnetic fields of stellarators, ion-temperature-gradient turbulence is shown to have two distinct saturation regimes, as revealed by petascale numerical simulations, and explained by a simple turbulence theory.

A Tokamak Ignition/Burn Experimental Research Device [PDF]

open access: yesFusion Technology, 1985
As part of a continuing effort by the Office of Fusion Energy to define an ignition experiment, a superconducting tokamak has been designed with thin neutron shielding and aggressive magnet and plasma parameters. By so minimizing the inner radial dimensions of the tokamak center post, coil, and shielding region, the plasma major radius is reduced with ...

A Drift-Kinetic Analytical Model for SOL Plasma Dynamics at Arbitrary Collisionality [PDF]

open access: yes, 2017
A drift-kinetic model to describe the plasma dynamics in the scrape-off layer region of tokamak devices at arbitrary collisionality is derived. Our formulation is based on a gyroaveraged Lagrangian description of the charged particle motion, and the ...

Parameter study of ICRH wave propagation in IShTAR [PDF]

open access: yes, 2016
A crude first assessment of how waves behave is commonly made relying on decoupled dispersion equation roots. In the low density, low temperature region behind the last closed flux surface in a tokamak where the density decays exponentially and where the

Research on three-phase four-wire NPC converter for Tokamak low-frequency resonance suppressor

open access: yesEnergy Reports, 2021
During the operation of Tokamak power system, a large number of low frequency harmonic currents with complex spectrum will be generated. Low-frequency resonance suppressor is an effective solution to suppress this low-frequency harmonic currents. The low-
