• We have examined the feasibility of alpha-particle diagnostics using a high energy neutral beam on the R-tokamak, a planned device at IPP-Nagoya, Japan, for reacting plasma experiments. In this method, injected neutral particles neutralize alpha particles so as to escape from the magnetically confined plasma through double charge exchange processes, He^<++>+A°⤑ He°+A^<++>. Requirements for a probing beam are discussed from viewpoints of penetration of an injected beam in the plasma and a neutralization efficiency of alpha particles in a wide velocity range. Either a Li°beam or a He°beam in the ground state, produced from a negative ion beam is suitable. A method to neutralize a He^- beam into the ground state through an auto-detachment process is proposed.
