The area of energetic particle (EP) physics in fusion research has been actively and
extensively researched in recent decades. The progress achieved in advancing and …

A review of the use of gamma ray spectrometry as a diagnostic of nuclear reaction rates and
nuclear reaction product densities in high temperature fusion plasmas is presented. In this …

On the road to a fusion reactor, a thorough control of the fast-ion distribution plays a crucial
role. Fusion-born α α-particles are, indeed, a necessary ingredient of self-sustained burning …

Combined neutral beam injection and fast wave heating at the fourth and fifth cyclotron
harmonics accelerate fast ions in the DIII-D tokamak. Measurements with a nine-channel fast …

The fusion reaction between deuterium and tritium, D (T, n) 4 He is the main source of
energy in future thermonuclear reactors. Alpha-particles (4 He-ions) born with an average …

High-resolution γ-ray spectroscopy (GRS) measurements resolve spectral shapes of
Doppler-broadened γ-rays. We calculate weight functions describing velocity-space …

We discuss α-particle velocity-space diagnostic in ITER based on the planned collective
Thomson scattering (CTS) and γ-ray spectrometry (GRS) systems as well as ASCOT …

Gamma-ray spectrometry on ITER can provide information both on confined fusion alpha
particles for optimization of plasma heating and runaway electrons, which is important for …

Recent upgrades to the FIDA (fast-ion D-alpha) diagnostic at ASDEX Upgrade allow to
reconstruct the fast-ion phase space at several radial positions with decent energy and pitch …

The spectral broadening of γ-rays from fusion plasmas can be measured in high-resolution
gamma-ray spectrometry (GRS). We derive weight functions that determine the observable …
