Advanced Neutral Particle Analyzer for Fusion Plasma Diagnostics

An advanced neutral particle analyzer for the diagnostics of hot plasma has been designed and fabricated in the Budker Institute of Nuclear Physics. The analyzer measures the ion energy distributions of both bulk plasma ions as well of fast ions created by neutral beam injection. The main feature of the analyzer is the ability to simultaneously measure hydrogen and deuterium atoms. The design of the analyzer, calculation of registration efficiency, and possible applications for plasma diagnostics on GOL-3 and GDT facilities are presented.
