Parametric study of controlled sawteeth for helium exhaust [PDF]

, 1991
Thermalized fusion born helium ash'' accumulation dilutes the reacting species and directly influences the viability of a desired fusion burn. Generally, several recent 0-dimentional investigations have shown that the ignition operating regime in n-T (or

Impurity radiation seeding of neoclassical tearing mode growth

Nuclear Fusion
The physics of neoclassical tearing modes (NTMs) is of great concern to tokamak plasma stability and performance, especially in the burning plasma regime.

Observation of Spontaneous Neoclassical Tearing Modes [PDF]

, 2001
We present data in this paper from the Tokamak Fusion Test Reactor (TFTR) which challenges the commonly held belief that extrinsic MHD events such as sawteeth or ELMs [edge localized modes] are required to provide the seed islands that trigger ...

Sawteeth and their stabilization in JET

, 1990
Sawtooth relaxations control the central plasma parameters in most JET discharges and, as a result, have a significant influence on fusion performance.

Radiation induced non-linear oscillations in ITER baseline scenario plasmas in DIII-D

Nuclear Fusion
This work shows how the radiation brought about by metals or metal-equivalent radiators such as Kr and Xe produces non-linear dynamics on otherwise stationary β _N flattops of DIII-D ITER Baseline Scenario demonstration discharges.

Modelling and experiment to stabilize disruptive tearing modes in the ITER baseline scenario in DIII-D

Nuclear Fusion
The achievement of high gain, stationary conditions in a tokamak scenario aimed at producing fusion energy in the ITER Project is crucial to the demonstration that this form of energy can be used in future reactors to provide cheap and clean energy ...

Overview of fast particle experiments in the first MAST Upgrade experimental campaigns

Nuclear Fusion
MAST-U is equipped with on-axis and off-axis neutral beam injectors (NBI), and these external sources of super-Alfvénic deuterium fast-ions provide opportunities for studying a wide range of phenomena relevant to the physics of alpha-particles in burning

Modeling the effect of MHD activity on runaway electron generation during SPARC disruptions

Nuclear Fusion
Magnetohydrodynamic (MHD) instabilities and runaway electrons (REs) interact in several ways, making it important to self-consistently model these interactions for accurate predictions of RE generation and the design of mitigation strategies, such as ...
