Implementation of synthetic fast-ion loss detector and imaging heavy ion beam probe diagnostics in the 3D hybrid kinetic-MHD code MEGA
(American Institute of Physics, 2021-04-27)
A synthetic fast-ion loss (FIL) detector and an imaging Heavy Ion Beam Probe (i-HIBP) have been implemented in the 3D hybrid kinetic-magnetohydrodynamic code MEGA. First synthetic measurements from these two diagnostics ...

Impact of β n and Spectrum of n = 1 Applied Fields on Fast ion Losses in DIII-D
(Institute of Physics Publishing, 2023)
The effect of n = 1 magnetic perturbations (MPs) on prompt fast ion losses in DIII-D has been investigated using the light ion beam probe technique. The effect of normalized beta, β n, and the plasma response to the MPs ...

First measurements of a magnetically driven fast-ion loss detector on ASDEX Upgrade
(Institute of Physics Publishing, 2019)
A new scintillator-based fast-ion loss detector (FILD) has been deployed ∼45ˆ below the midplane of the ASDEX Upgrade tokamak. Port unavailability at this remote location requires an in-situ magnetically driven manipulator ...
