Summary on Grant Application Form
High resolution X-ray spectroscopy is of major importance in many areas of plasma physics and astrophysics, and the analyses of such observations using spectral modelling codes provide vital information on a range of plasma properties. However a major limitation to spectral modelling codes is that we do not know a priori if they are producing accurate theoretical results, and hence if we can perform a reliable analysis of experimental spectra. In principle, one can ensure that such codes are producing accurate results if the model predictions can be directly benchmarked against experimental data obtained via well-diagnosed laboratory experiments under known plasma conditions. However, the photoionization-dominated regime has been inaccessible to laboratory experiments - until now.We are part of a major consortium, involving physicists at the Lawrence Livermore and Sandia National Laboratories, to run experiments on the Z Machine at Sandia with the precise aim of benchmarking, for the first time, plasma modelling codes, including NIMP and GALAXY, which are used extensively in the UK to model the X-ray spectra of plasmas. In this proposal we seek funding for UK participation in this exciting, unique project. Specifically, we require postdoctoral support to undertake an extensive programme of atomic physics calculations for Fe XVII through Fe XXVI, vitally required as input to modelling codes to reliably analyse the Sandia X-ray spectra. We also wish to perform a detailed comparison of NIMP and GALAXY simulations with the Sandia observations, to fully benchmark our codes.
