tFusion alpha particle diagnostics for ITER remain a challenging task. Standard escaping alpha particledetectors in present tokamaks are not applicable to ITER and techniques suitable for fusion reactor con-ditions need further research and development [1,2]. The activation technique is widely used for thecharacterization of high fluence rates inside neutron reactors. Tokamak applications of the neutron acti-vation technique are already well developed [3] whereas measuring escaping ions using this techniqueis a novel fusion plasma diagnostic development. Despite low alpha particle fluence levels in presenttokamaks, promising results using activation technique combined with ultra-low level gamma-ray spec-trometry [4] were achieved before in JET [5,6].
