Two sight lines, one tangential and the other perpendicular, are examined as candidates. It was found that the tangential one has better sensitivity than the perpendicular one. A trial of the FIDA measurement was performed on JT-60U. Signals due to the tangential-NB injection were obtained. It was found that about the one third of the signal would be due to the active FIDA signal, which was produced by fast-ions and a probe beam, while the remainder would be due to passive signal. The results indicate the FIDA measurement on JT-60SA would be possible with proper background measurements.}, title = {A Plan for a Fast-Ion D-Alpha (FIDA) Measurement for JT-60SA}, volume = {8}, year = {2013} }
