Placement of a fast ion loss detector array for neutral beam injected particles in Wendelstein 7-X

Fast ion confinement and stability in a neutral beam injected reversed field pinch

Wendelstein 7-X and fusion

Modeling the response of a fast ion loss detector using orbit tracing techniques in a neutral beam prompt-loss study on the DIII-D tokamak.

A numerical model describing the expected measurements of neutral beam prompt-losses by a newly commissioned fast ion loss detector (FILD) in DIII-D is presented. This model incorporates the well understood neutral beam deposition profiles from all eight DIII-D beamlines to construct a prompt-loss source distribution. The full range of detectable ion orbit phase space available to the FILD is u...

A New Dispersion Interferometer for the Stellarator Wendelstein 7-X

Modeling of ion-cyclotron resonant heating in Wendelstein 7-X equilibrium

W7X stellarator 3D equilibrium has been computed with the equilibrium code ANIMEC (Anisotropic Neumann Inverse Moments Equilibrium Code). This equilibrium was used to model ICRH minority heating in 4 He(H) plasma with the 3D full-wave code LEMan (Low frequency ElectroMagnetic wave propagation). The coupled power spatial distribution is shown for different resonance positions within the range of...
