Abstract

Spectral line shifts have been observed in the D-alpha transition of neutral deuterium in the Alcator C-mod [I. H. Hutchinson, Proceedings of the IEEE 13th Symposium on Fusion Engineering (IEEE, Piscataway, 1990), Vol. 1, p.13] tokamak and interpreted as Doppler shifts due to a neutral flow of approximately 5x10(3) m/s. The emission originates from plasma at the inner wall, as indicated by the Zeeman patterns of the transition. The direction ofthe flow changes when the plasma transitions from a limited to a diverted configuration. In all cases, the flows are directed toward the point of contact with the wall or divertor plate. Narrow spectral profiles have been observed for the D-alpha transition near the midplane and within the divertor. Temperatures not higher than 0.86 eV are indicated for the divertor measurements. A difference in plasma conditions for separate locations along a single line of sight has been observed. (C) 2001 American Institute of Physics.
