Recent Progress in Fast-Ion Physics on JET

摘要: This paper presents recent results on fast-ion studies in JET. The unique diagnostic set for confined and lost particle was utilised to investigate the response of fast ions MHD modes toroidal field (TF) ripple, He-ions behaviour shear-reversed plasmas. A dependence loss intensity vs. mode amplitude derived from experiments. study various plasma scenarios has shown that a significant redistribution happens during change profile safety factor strongly monotonic. It found changes losses ICRH accelerated protons are associated with confinement transitions After an L-H transition, abrupt decrease proton observed. In plasmas internal transport barrier, ICRH-accelerated increases as barrier forms. Further concerning ion were obtained JET experiments which magnitude TF ripple varied. fusion products high triangularity appear similar classical losses, agreement modelling.
