In the TEXTOR tokamak, the Doppler broadening of spectral lines, emitted by the recycling atoms in front of a limiter, have been measured to derive the distribution of their radial velocity component. When the carbon limiter is replaced by a steel limiter, the line profile changes in accord with the increased particle reflection coefficient of steel.
