Fast ions with energies significantly larger than the bulk ion temperature are used to heat
most tokamak plasmas. Fast ion populations created by fusion reactions, by neutral beam …

Strong magnetohydrodynamic activity has been observed in PDX neutral-beam-heated
discharges. It occurs for β T q>~ 0.045 and is associated with a significant loss of fast ions …

Neutron diagnostics are of increasing importance for future fusion devices. Consequently,
efforts are being made to improve the accuracy of underlying experimental and …

Experiments in the DIII-D tokamak show that fast-ion transport suddenly becomes stiff above
a critical threshold in the presence of many overlapping small-amplitude Alfvén eigenmodes …

A simulation of an anticipated TFTR deuterium-tritium supershot is described. The simulation
is based on a reproducible, high performance, long duration D-only supershot. The TRANSP …

The deuterium operation of the large helical device (LHD) heliotron started in March 7, 2017,
after long-term preparation and commissioning works necessary to execute the deuterium …

Short deuterium beam pulses are injected into the D III–D tokamak to study the variation of
beam slowingdown time with temperature and density. The slowing-down time is inferred …

Because magnetically confined plasmas are generally not found in a state of thermodynamic
equilibrium, they have been studied extensively with methods of applied kinetic theory. In …

Quasilinear gyrokinetic calculations of the transport of fast α particles with a slowing-down
equilibrium distribution function in the trace limit are presented. Diffusive and convective …

Although the stability of ellipticity, toroidal and reversed-shear Alfvén eigenmodes (EAE,
TAE, RSAE) are relatively well understood, less is known about the stability of lower …
