Abstract:

The temperature profile of a self-absorbing radially symmetric cylindrical laboratory plasma was experimentally determined using a spectroradiometric technique. The technique involves the measurement of the ratio of the spectral radiant emittance of the plasma gas to its spectral absorptivity which, according to Kirchhoffs law, is equal to the spectral radiant emittance of a black body at the same temperature and wavelength. The method does not depend on knowledge of the transition probabilities or number densities of the gas under study, or even its composition, and it is valid whenever departures from local thermal equilibrium in the plasma are small.
