A model for Alfvén-eigenmode-induced transport of fast ions in stellarators

Nuclear Fusion
A novel model for Alfvén-eigenmode-induced transport of fast ions in stellarators is introduced. A variety of reduced transport models exists for tokamaks, but nothing comparable currently exists for stellarators.

Hybrid kinetic-MHD modeling of alpha-driven TAEs in the SPARC tokamak

Nuclear Fusion
As the magnetic confinement fusion community prepares for the next generation of fusion devices and burning plasmas, there is still a question of whether fast ions (FIs) will drive MHD instabilities, causing significant redistribution or even loss of FIs,

Overview of fast particle experiments in the first MAST Upgrade experimental campaigns

Nuclear Fusion
MAST-U is equipped with on-axis and off-axis neutral beam injectors (NBI), and these external sources of super-Alfvénic deuterium fast-ions provide opportunities for studying a wide range of phenomena relevant to the physics of alpha-particles in burning

Development of slow and fast wave coupling and heating from the C-Stellarator to NSTX

EPJ Web of Conferences, 2017
A historical perspective on key discoveries which contributed to understanding the properties of coupling both slow and fast waves and the effects on plasma heating and current drive will be presented.

Observation of multiple beta-induced Alfvén eigenmodes driven by runaway electrons in EAST Ohmic discharge

Nuclear Fusion
Multiple Beta-induced Alfvén eigenmodes (BAEs) excited by runaway electrons (REs) have been observed in low-density Ohmic discharges in the EAST tokamak.
