Abstract
In the Experimental Advanced Superconducting Tokamak (EAST), a vertically and a tangentially viewing fast-ion D-alpha (FIDA) diagnostics have been installed in order to investigate fast-ion dynamics. This is done by measuring the Doppler-shifted D-alpha light arising due to charge exchange between a neutral beam and the fast ions. By combining measurements from both FIDA instruments, the fast-ion velocity distribution can be obtained by velocity-space tomography. To explore the possibilities and limitations of velocity-space tomography in studying the fast-ion distribution in EAST, we present reconstructions of the fast-ion velocity distribution from synthetic FIDA measurements.
