Abstract

The modelling of distribution functions of alphas produced in JET by NBI blips of tritium into deuterium plasmas demonstrated the importance of source energy spectrum broadening and its anisotropy for alpha relaxation. First orbit losses and radial transport affect the alpha relaxation and are shown to reduce the delay time of alpha induced gamma emission. However, additional loss mechanisms should be accounted for to match the modelling with the measurements. An unambiguous study of gamma emission evolution requires multichord measurements with reasonable time resolution (small as compared to alpha slowing down time).
