Résumé

High-resolution -ray measurements were carried out on the Joint European Torus (JET) in an experiment aimed at accelerating ⁴He ions in the MeV range by coupling third harmonic radio frequency heating to an injected ⁴He beam. For the first time, Doppler broadening of -ray peaks from the ¹²C(d, p) ¹³C and ⁹Be(, n) ¹²C reactions was observed and interpreted with dedicated Monte Carlo codes based on the detailed nuclear physics of the processes. Information on the confined ⁴He and deuteron energy distribution was inferred, and confined ⁴He ions with energies as high as 6MeV were assessed. A signature of MHD activity in -ray traces was also detected. The reported results have a bearing on diagnostics for fast ions in the MeV range in next step fusion devices.
