FIG. 1.

Top: measurement. Bottom: simulation. Shown here is a typical example of a helium spectrum of TEXTOR, compared with the results of the simulation code. In both cases the signal-to-noise ratio is comparable ( at half width).

FIG. 2.

High resolution high etendue echelle spectrometer, developed at TRINITI. Elements: slit, flat mirror, mirror, mirror with hole, element, grating, and plane.

Image of FIG. 3.
FIG. 3.

The helium density determined from the increase in the electron density after a puff (single data point), and from the ratio of CXRS and BES intensities (upper line with data points). Within the error bar, agreement is obtained. (The electron density is given by the lower line).

Image of FIG. 4.
FIG. 4.

Measured beam emission at the edge (top) and in the center (bottom) of the plasma. A clear difference in the ratio between the and intensity is observed.

Image of FIG. 5.
FIG. 5.

The line ratio for two case with opposite current [i.e., where the sign in Eq. (2) changes]. The effect of the mirror is to make the measurement less sensitive. Nevertheless, experimental data show the expected trend.
