Effects of CT injector acceleration electrode configuration on tokamak penetration [PDF]
Through compact toroid (CT) injection experiments on the TEXT-U tokamak (with BT simeq 10 kG and IP simeq 100 kA), it has been shown that the acceleration electrode configuration, particularly in the vicinity of the toroidal field (TF) coils of the ...

Large density amplification measured on jets ejected from a magnetized plasma gun [PDF]
Observation of a large density amplification in the collimating plasma jet ejected from a coplanar coaxial plasma gun is reported. The jet velocity is ~30 km s^-1 and the electron density increases from ~10^20 to 10^(22–23) m^-3.

Low n electromagnetic modes in spherical tokamaks
Abstract The performance of spherical tokamak reactors depends on plasma β, and an upper limit is set by long-wavelength kinetic ballooning modes (KBMs). We examine how these modes become unstable in spherical-tokamak reactor relevant plasmas, which may contain significant fast-ion pressure.

Studies of various lower hybrid wave launch scenarios for non-inductive start-up on TST-2 [PDF]
Efficient 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 ...

On non existence of tokamak equilibria with purely poloidal flow [PDF]
It is proved that irrespective of compressibility tokamak steady states with purely poloidal mass flow can not exist in the framework of either magnetohydrodynamics (MHD) or Hall MHD models.

Control of resistive wall modes in the spherical tokamak
In this work, the MARS-F/K codes (Liu et al 2000 Phys. Plasmas 7 3681; Liu et al 2008 Phys. Plasmas 15 112503) are utilized to model the passive and active control of the n = 1 ( n is the toroidal mode number) resistive wall mode (RWM) in a spherical ...

Formation of convective cells in the scrape-off layer of the CASTOR tokamak [PDF]
Understanding of the scrape-off layer (SOL) physics in tokamaks requires diagnostics with sufficient temporal and spatial resolution. This contribution describes results of experiments performed in the SOL of the CASTOR tokamak (R=40 cm, a = 6 cm) by ...
