Invited

Energetic-ion redistribution and loss induced by MHD activity are critical issues for present fusion experiments and future burning plasmas [1,2]. In future fusion power plants, energetic-particle diagnostics must operate in reactor-relevant environments where access, neutron/gamma radiation, and the use of active beam-based measurements may be limited. Radio-frequency diagnostics are...

67. Investigation of Fast-Ion Velocity Distribution Functions via Neutron Emission Spectroscopy on EAST

Oral

This report presents an overview of the experimental results and data processing advancements in fast-ion diagnostics using neutron emission spectroscopy (NES) on the EAST tokamak.

The EAST NES system comprises multiple spectrometers arranged along four lines of sight (LOS), including a time-of-flight enhanced diagnostic (TOFED), a stilbene crystal, three liquid scintillators, a CLYC, a...

EPs in stellarators and 3D configurations I

Oral

Studying the mechanisms of energetic α-particle slowing down, redistribution and the development of optimal plasma conditions for their confinement is a priority task for burning fusion reactors. The harsh radiation environment of deuterium-tritium (D-T) fusion reactors makes realisation of this task extremely difficult since a restricted set of plasma diagnostics will be available. In this...

68. Qualitative validation of CAD-based simulations of NBI-induced prompt fast-ion losses against IRTV measurements in KSTAR

Poster session I

Oral

Modern devices such as KSTAR and ITER are crowded with heating ports, cooling channels, and diagnostics, and rely on auxiliary heating such as neutral beam injection (NBI), so that beam power deposition and the resulting plasma-facing component (PFC) heat loads are governed by real, non-axisymmetric engineering geometry that idealized toroidally symmetric models cannot capture....
