Boundary plasma studies for a spherical tokamak with lithium walls
Nuclear Materials and EnergyBoundary plasma and plasma-material interactions are investigated for magnetised target fusion (MTF) applications. The General Fusion magnetised target fusion technology uses coaxial helicity injection (CHI) start-up which forms a spherical tokamak in a ...

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 ...

Design of vacuum system for NCST spherical tokamak
AIP Advances, 2023 The NanChang Spherical Tokamak (NCST) is a new compact tokamak with an aspect ratio of R/a = 1.67. The vacuum system is one of the most important sub-systems of the tokamak device and has been designed especially for the NCST device. It consists of three

Studies of various lower hybrid wave launch scenarios for non-inductive start-up on TST-2 [PDF]
EPJ Web of ConferencesEfficient non-inductive start-up of a spherical tokamak may be achieved by using lower hybrid waves that have high current drive efficiency. On the TST-2 spherical tokamak, three lower hybrid launchers are installed at the outer-midplane, top and outer ...

Gyrokinetic simulations of spherical tokamaks [PDF]
Plasma Physics and Controlled Fusion, 2009 This paper reviews transport and confinement in spherical tokamaks (STs) and our current physics understanding of this that is partly based on gyrokinetic simulations. Equilibrium flow shear plays an important role, and we show how this is consistently included in the gyrokinetic framework for flows that greatly exceed the diamagnetic velocity. The key
