MeV ion losses measurements in JET using activation technique

Measurements of energetic particle losses from the plasma, in particular alpha particles, remain difficult in large fusion devices and further R&D is needed in view of ITER[13]. The present paper describes new measurements using activation technique[1, 2, 3]. Samples are activated due to nuclear reactions of type (X,n), (X,γ),... where X is a light charged particle p,t,d,3h
