Direct measurement of MeV-range atomic hydrogen using a charge-exchange neutral particle analyzer in ICRF-heated JT-60U plasmas

Abstract

The energetic atomic hydrogen in an MeV range produced by the ion cyclotron range of frequency heating in JT-60U plasma was directly measured with a charge-exchange neutral particle analyzer. Particle signals from the detector were successfully separated from the neutron and {gamma} ray background by the pulse height analysis (PHA) method used first in all detector channels. The net flux of atomic hydrogen was easily obtained by summing counted numbers of PHA channels over the peak formed by atomic hydrogen. (author).
