Description
Production, confinement and thermalization of high-energy particles are the fundamental issues in fusion plasma ion kinetics. The ion distribution function ft(ν, θ, t) and its evolution under the ion cyclotron heating (ICH) and neutral beam injection (NBI) are studied by energy resolved charge exchange neutral particle flux measurements. For helical systems, such as LHD, local diagnostics are required due to the complex 3D magnetic configuration. First radially resolved measurements of local H0 atomic energy spectra have been made on LHD by the pellet charge exchange (PCX) method with a Compact Neutral Particle Analyzer (CNPA). The diagnostic technique, the initial measurement results in the range 10-100 keV and the data analysis are described. (author)
