Transport Simulasion in a Burning Tokamak Plasma [PDF]

, 1992
A one-dimensional tokamak transport code (TASK/TR) has been developed to analyze the evolution of a burning plasma accompanied with fusion reaction. This code deals with the electrons, deuterons, tritons, thermalized α particles, fast α particles and ...

Progress in the pre-conceptual design of the auxiliary heating and current drive system for the Tokamak Energy Fusion Pilot Plant [PDF]

EPJ Web of Conferences
Auxiliary heating and current drive is a crucial aspect of reactor-relevant tokamaks. Tokamak Energy is currently in the design phase of their Fusion Pilot Plant (FPP). Initial investigations for the flat-top phase of plasma scenarios rely exclusively on

Achievement of ion temperatures in excess of 100 million degrees Kelvin in the compact high-field spherical tokamak ST40

Nuclear Fusion, 2023
Ion temperatures of over 100 million degrees Kelvin (8.6 keV) have been produced in the ST40 compact high-field spherical tokamak (ST). Ion temperatures in excess of 5 keV have not previously been reached in any ST and have only been obtained in much ...

On The Confinement of a Tokamak Plasma [PDF]

SIAM Journal on Mathematical Analysis, 2010
The goal of this paper is to understand from a mathematical point of view the magnetic confinement of plasmas for fusion. Following Frénod and Sonnendrücker \cite{FS2}, we first use two-scale convergence tools to derive a gyrokinetic system for a plasma submitted to a large magnetic field with a slowly spatially varying intensity.

Interplay between beam-driven chirping modes and plasma confinement transitions in spherical tokamak ST40

Nuclear Fusion, 2022
Experiments on the high field spherical tokamak ST40 have led to the recent observation of interplay between beam-driven modes of sweeping frequency (chirping modes) and transitions to the enhanced global confinement regime (H-mode) and back to the low ...

Modelling for JET Vertical Stabilization System [PDF]

, 2010
Nuclear fusion is, in a sense, the opposite of nuclear fission. Fission, which is a mature technology, produces energy through the splitting of heavy atoms like uranium in controlled chain reactions.
