Recent progress on improving ICRF coupling and reducing RF-specific impurities in ASDEX Upgrade

EPJ Web of Conferences, 2017
The recent scientific research on ASDEX Upgrade (AUG) has greatly advanced solutions to two issues of Radio Frequency (RF) heating in the Ion Cyclotron Range of Frequencies (ICRF): (a) the coupling of ICRF power to the plasma is significantly improved by

Anisotropic regularization for inversion of fast-ion loss detector measurements

Nuclear Fusion
We introduce an anisotropic regularization framework for the reconstruction of distribution functions from measurements, utilizing an approach that applies distinct regularization techniques such as non-negative constrained Tikhonov, total variation, and
