摘要: This article reports on γ-ray diagnosis of ICRF-accelerated 4He ions and fusion α particles used in the JET tokamak. diagnostic based analysis γ rays emitted nuclear reaction 9Be(α,nγ)12C. The results first observation 4.44-MeV γ-radiation due to 9Be(α,nγ)12C deuterium–tritium experiment (DTE1) are presented. Gamma-ray spectra have been recorded with collimated spectrometer, emission radial profiles measured neutron/gamma profile monitor. Doppler broadening effects which could be for 4He-ion high energy resolution detectors discussed. Capabilities measurements next step D–T devices
