{sup 3}He ions with energies from thermal values up to 300 keV produced by ICRF heating have been spectroscopically observed by the {alpha}-CHERS diagnostic on TFTR. The shape of the spectrum and the temporal and spatial behavior of the energetic {sup 3}He ion emission are consistent with expectations for this ICRF heating case. Because the {sup 3}He ion density was similar to the alpha particle density predicted for D-T super shots on TFTR, these observations give confidence that confined alphas produced by D-T fusion reaction can be observed by {alpha}-CHERS during D-T operation of TFTR.
