Experiments on the behavior of light impurities in the plasma of the L-2 stellarator are reported. The diagnostic apparatus used for chord measurements of the emission intensity in the ion lines is described. The method for converting the results of these measurements to the local intensity is also described. The experimental results are used along with numerical calculations to estimate the electron temperature in the region corresponding to the maximum emission of the impurity ions. This temperature is found to be half the ionization potential of the ion. The electron temperature profile at the periphery of the plasma column is constructed from the spectral measurements. The dynamics of this profile in several operating regimes of the L-2 is studied.
