X-ray line transfer in plasmas with large velocity gradients
ASTROPHYS SPACE SCI 298:1-2 (2005) 171-176
Abstract:
An astrophysically relevant experiment is compared to the output of a multidimensional radiation transfer code in which populations and radiation are self-consistently treated. Experimental Al Ly alpha spectra obtained with a very high-resolution spectrometer are presented as quantitative evidence of dot plasma non-planar expansion. Analysis of these spectra using the code is performed, in particular examining the effects of velocity gradients in directions other than that of the primary expansion. These calculations are found to be in good agreement with the experimental results. Usage of the Ly alpha doublet as a planarity diagnostic is discussed.Rapid heating of solid density material by a petawatt laser
Applied Physics Letters 86:19 (2005) 1-3
Abstract:
Time-resolved x-ray spectra from solid targets irradiated by the VULCAN Petawatt laser focused to 1020 W cm-2 show that material at solid density is heated to temperatures above 500 eV to a depth of about 15 μm and for a duration of more than 30 ps. Modeling with the implicit hybrid plasma code LSP shows that the heating is sensitive to the laser prepulse through resistive inhibition of the laser accelerated electrons in the blow off layer. © 2005 American Institute of Physics.Energy levels and transition probabilities for nitrogen-like Fe xx***
