Quantitative study of inhomogeneities in an aluminum plasma using monochromatic imagery
Abstract
Inhomogeneities in plasma parameters and their effect in gain for different amplifitation schemes are studied. Monochromatic image diagnosis is used to quantify a 300 mm long aluminum plasma. The quantitative diagnosis method is shown to work well for large scale plasmas. Large inhomogeneity is found in the plasma parameters due to radiation quality. Large scale inhomogeneities directly related to variations in illumination are studied. Combining the diagnostic method with spatial resolution allows high frequency fluctuation effects to be studied quantitatively.
