Breakdown of adiabatic invariance in spherical tokamaks [PDF]
, 2001 Thermal ions in spherical tokamaks have two adiabatic invariants: the magnetic moment and the longitudinal invariant. For hot ions, variations in magnetic-field strength over a gyro period can become sufficiently large to cause breakdown of the adiabatic

Disruption prediction for future tokamaks using parameter-based transfer learning
Communications Physics, 2023 Tokamaks are the most promising way for nuclear fusion reactors. Disruption in tokamaks is a violent event that terminates a confined plasma and causes unacceptable damage to the device.

Experimental study of electron cyclotron heating assisted start-up on J-TEXT
Nuclear Fusion, 2023 Second harmonic X-mode (X2 mode) electron cyclotron heating (ECH) assisted start-up has been studied experimentally on the J-TEXT device to determine the minimum ECH power requirements to assist breakdown and develop a better physical description of the ...

Magneto-electrostatic trapping of ground state OH molecules [PDF]
, 2007 We report the magnetic confinement of neutral, ground state hydroxyl radicals (OH) at a density of $\sim3\times10^{3}$ cm$^{-3}$ and temperature of $\sim$30 mK.

On essential self-adjointness for magnetic Schroedinger and Pauli operators on the unit disc in R^2
, 2011 We study the question of magnetic confinement of quantum particles on the unit disk $\ID$ in $\IR^2$, i.e. we wish to achieve confinement solely by means of the growth of the magnetic field $B(\vec x)$ near the boundary of the disk.

Tilting instability of magnetically confined spheromaks [PDF]
Journal of Plasma Physics, 2020 We consider the tilting instability of a magnetically confined spheromak using three-dimensional magnetohydrodynamic and relativistic particle-in-cell calculations with an application to astrophysical plasmas, specifically those occurring in magnetar magnetospheres.

Dirac Fermion Confinement in Graphene
, 2006 We study the problem of Dirac fermion confinement in graphene in the presence of a perpendicular magnetic field B. We show, analytically and numerically, that confinement leads to anomalies in the electronic spectrum and to a magnetic field dependent ...

Spectra of magnetic perturbations triggered by pellets in JET plasmas [PDF]
, 2010 Aiming at investigating edge localised mode (ELM) pacing for future application on ITER, experiments have been conducted on JET injecting pellets in different plasma configurations, including high confinement regimes with type-I and type-III ELMs, low ...

Polar confinement of the Sun's interior magnetic field by laminar magnetostrophic flow
, 2011 The global-scale interior magnetic field needed to account for the Sun's observed differential rotation can be effective only if confined below the convection zone in all latitudes, including the polar caps.
