N2 - Confined alpha particles can be measurement in ITER by injecting energetic He0 (ground state) beam to neutralize alphas in the plasma. It was experimentally confirmed that auto-detachment of a He- beam produces a ground state He0 beam through the Time Of Flight (TOF) neuralization. A full size strong-focusing He+ ion source was developed, and a beam current higher than 2A was achieved with the minimum beam radius of 11.3 mm, at the beam energy of 20 - 25 keV, which is suitable to be converted to He- in an alkali vapour.
