Alpha particles will interact with the ablation cloud surrounding an injected pellet via charge-exchange (CX) and nuclear reactions. The use of these interactions to diagnose fast confined alphas in a fusion plasma is discussed. Measurement of helium neutrals from multiple CX interactions should allow determination of the incident alpha-energy distribution.
