ABSTRACT
A number of alpha-particle diagnostics were initiated successfully during the TFTR DT phase. These diagnostics were prototypical and were not able to operate under all conditions. Had TFTR continued to operate, the deficiencies should have been corrected. Effects of radiation on fiberoptics and other components, lack of sufficient power in collective scattering and the effects of neutral beams on pellet ablation impacting pellet charge-exchange were specific deficiencies in alpha—particle diagnostics. For understanding of the alpha source profile, the importance of very detailed calibrations of neutron diagnostics must be stressed. The interactions of fast ions with instabilities have been taken further in later devices but some aspects were already clear in the DT phase.
