Spherical tokamaks (STs) typically have lower magnetic fields than conventional tokamaks,
but similar mass densities. Suprathermal ions with relatively modest energies, in particular …

In the last three years, magnetic reconnection research in the MAST spherical tokamak
achieved major progress by the use of new 32 chord ion Doppler tomography and 130 …

Electron and ion heating characteristics during merging reconnection start-up on the MAST
spherical tokamak have been revealed in detail using a 130 channel yttrium aluminum …

Merging-compression is a solenoid-free plasma formation method used in spherical
tokamaks (STs). Two plasma rings are formed and merged via magnetic reconnection into …

Within the resistive magnetohydrodynamic model, high-Lundquist number reconnection
layers are unstable to the plasmoid instability, leading to a turbulent evolution where the …

Abstract Space plasma simulations have seen an increase in the use of
magnetohydrodynamic (MHD) with embedded Particle-in-Cell (PIC) models. This combined …

We present results of recent studies of merging/reconnection heating during central solenoid
(CS)-free plasma startup in the Mega Amp Spherical Tokamak (MAST). During this process …

Realistic models of magnetic reconnection in the solar chromosphere must take into account
that the plasma is partially ionized and that plasma conditions within any two magnetic flux …

Oscillatory reconnection is a process that has been suggested to underlie several solar and
stellar phenomena, and is likely to play an important role in transient events such as flares …

Ion heating/transport and its fine structure formation process through magnetic reconnection
have been investigated by high guide field tokamak merging experiments in TS-3 and TS …
