Measurement of D(alpha) sources for particle confinement time determination in TEXTOR
A CCD video camera has been used to perform quantitative measurements of D(alpha) emission in TEXTOR. This method offers advantages over measurements with spot detectors. It is found that the emission from a halo around the limiter belt is of the same order as that in front of the limiter and must be taken into account in determining the total D(alpha) emission from the discharge. The emission increases with the particle content of the plasma, which is inconsistent with a confinement time proportional to density.
