Helium removal from tokamaks

Plasma Physics and Controlled Fusion, 1991
Helium, as the ash of burning D-T plasma, is an unavoidable impurity component necessarily present already in near future tokamak experiments with significant alpha particle heating. Its efficient removal from the burning zone of a D-T fusion reactor plays a key role in the path towards achievement of economic fusion power production. A survey is given

Neutron Energy Spectrum Measurements with a Compact Liquid Scintillation Detector on EAST

, 2013
A neutron detector based on EJ301 liquid scintillator has been employed at EAST to measure the neutron energy spectrum for D-D fusion plasma. The detector was carefully characterized in different quasi-monoenergetic neutron fields generated by a 4.5 MV ...

Reconstruction of the equilibrium of the plasma in a Tokamak and identification of the current density profile in real time [PDF]

, 2011
The reconstruction of the equilibrium of a plasma in a Tokamak is a free boundary problem described by the Grad-Shafranov equation in axisymmetric configuration.

Structure of chaotic magnetic field lines in IR-T1 tokamak due to ergodic magnetic limiter

AIP Advances, 2018
In this paper we have studied an Ergodic Magnetic Limiter (EML) based chaotic magnetic field for transport control in the edge plasma of IR-T1 tokamak. The resonance created by the EML causes perturbation of the equilibrium field line in tokamak and as a

Study of an improved single neuron PID control algorithm in the Tokamak plasma density control system

Measurement + Control
Tokamak is an important device for controlled nuclear fusion research. The plasma electronic density control system (PEDCS) is an important system for controlling the Tokamak discharge process, which should be of high stability, rapidity, and accuracy ...

Non-Axisymmetric Tokamak Plasma Equilibrium by 3-D Multi-Layers Method

Applied Sciences
A three-dimensional (3-D) Multi-Layers Method (MLM) of an extension of the axisymmetric version has been developed to compute non-axisymmetric tokamak plasma equilibria with a separatrix.

Mechanical model for a full fusion tokamak enabled by supercomputing

Nuclear Fusion
Determining stress and strain in a component of a fusion power plant involves defining boundary conditions for the mechanical equilibrium equations, which implies the availability of a full reactor model for defining those conditions.
