Outline of Final Research Achievements

The purpose of this research is to study 3.5MeV alpha particle confinement and its physics created by DT reaction in burning plasmas. For the diagnostic of alpha particle loss to a first wall in a fusion reactor, we proposed and developed an alpha particle induced gamma ray spectroscopy. A pixel detector has been developed to acquire 4.44MeV gamma ray from the reaction of Be-alpha. We measured the gamma ray image successfully using it. Simultaneously a Ge detector detected the high resolution energy spectrum of 4.44 MeV gamma ray. We found that the spectrum has an angular dependence of the Doppler broadening strongly.
