FIG. 1.

Radiance spectrum for a vertical chord passing through at the plasma midplane. The upper spectrum was taken during a neutral beam pulse with the beam energy of . The lower spectrum was taken after the beam was turned off. Note that both of the lines are enhanced by active charge exchange.

FIG. 2.

Effective emission rate for 4944.67 . The main energy component of the beam dominates for energies in the range, but there are significant contributions from the other beam energy components.

FIG. 3.

The contributions to the total emission rates of and transitions for one location in the plasma are shown. Contributions from each of the beam components and from each of the excited states are identified.

FIG. 4.

Apparent error in density measurement. First model assumes that the neutrals are entirely in the ground state . The second model adds first excited state . The third model includes ground state and the first two excited states .

FIG. 5.

Measured density profiles for . Each of the points represents the experiment with the similar plasma conditions, but the measurement is made with the different beam energies. Fitted line is intended to guide the eyes.
