摘要: In ITER, α particle loss measurements will be required in order to understand the alpha physics. Techniques capable of operating a fusion reactor environment need further development. Recent experimental studies on JET demonstrated potential nuclear activation measure flux escaping MeV ions. New results from ion induced metallic, ceramic, and crystal samples placed near plasma edge are reported. Activation products were measured as function orientation with respect magnetic field well distance plasma. Sample activity was using ultralow-level gamma-ray spectrometry. Distribution 14.68 proton is strongly anisotropic agreement simulations falls off sharply increasing Prospects for technique ITER discussed.
