X-ray-transport effects in laser-irradiated disks
Abstract
X-ray emission spectra are important diagnostics for studying laser coupling and energy transport. The sensitivity of such measurements to the plasma density and temperature profiles are explored. The one dimensional radiation transport equation is solved for various temperature and density profiles. Spectra are calculated in both the LTE and CRE approximations, bracketing the relevant regimes. Their applicability to real plasmas is discussed. The calculated spectra are compared with measurements from different Z targets. This comparison explores the possible temperature and density parameters. Such comparisons can be used to interpret experimental results as well as guide the design of experiments.
