The interpretation of density sensitive line diagnostics from inhomogeneous plasmas. II - Non-isothermal plasmas
Abstract
The formulation of the problem of inferring density structure in inhomogeneous nonisothermal plasmas is generalized here to cases where both the density n and temperature T are inhomogeneous. It is shown how the concepts of emission measure differential in T and n can be extended to arbitrary plasmas. It is demonstrated how in the special degenerate case where surfaces of constant T and constant n coincide it is possible to utilize jointly data on temperature and density-sensitive line ratios to draw conclusions concerning the plasma pressure distribution.
