Abstract

Helium-3 ions with energies from thermal values up to 300 keV produced by ICRF heating have been spectroscopically observed by the α-CHERS diagnostic on the Tokamak Fusion Test Reactor (TFTR). The shape of the spectrum and the temporal and spatial behaviour of the energetic 3He ion emission are consistent with expectations for this ICRF heating case. Because the 3He ion density was similar to the alpha particle density predicted for D-T supershots on TFTR, these observations give confidence that confined alphas produced by D-T fusion reactions can be observed by α-CHERS during D-T operation of TFTR.
