Journal ArticleDOI
Quantitative measurement of mid-z opacities
Ted Perry,Kimberly S. Budil,R. Cauble,R. A. Ward,D. R. Bach,Carlos A. Iglesias,Brian G. Wilson,J.K. Nash,C.C. Smith,John Foster,S.J. Davidson,F. J. D. Serduke,J. D. Kilkenny,Richard W. Lee +13 more
TL;DR: In this paper, a general discussion of the experimental technique is given showing the requirements that must be met in order to extract quantitative transmission data and the resulting spectrally resolved absorption measurements can then be used to test the capabilities of LTE opacity codes.
Journal ArticleDOI
Opacity measurements: Extending the range and filling in the gaps
Christina Back,Ted Perry,D. R. Bach,Brian G. Wilson,Carlos A. Iglesias,Otto Landen,S.J. Davidson,B.J.B. Crowley +7 more
TL;DR: In this paper, a series of experiments to explore Ge opacity at temperatures where the M-shell is almost filled was discussed and data were obtained at lower temperatures than previously explored and allow to investigate the role of atomic structure calculations and their impact on opacity scalings.
Journal ArticleDOI
Heating of buried layer targets by 1ω and 2ω pulses using the HELEN CPA laser
D.J. Hoarty,Steven James,H. M. Davies,C. R. D. Brown,J.W.O. Harris,C.C. Smith,S.J. Davidson,E. Kerswill,B.J.B. Crowley,S. J. Rose +9 more
TL;DR: In this article, a target with a buried layer of aluminium was used to estimate the conditions in the target by comparing the measured spectra against synthetic spectra generated by the FLY code.
Journal ArticleDOI
Measurements of niobium absorption spectra in plasmas with nearly full M-shell configurations
D.J. Hoarty,J.W.O. Harris,P. Graham,S.J. Davidson,Steven James,B.J.B. Crowley,E. L. Clark,C.C. Smith,L.M. Upcraft +8 more
TL;DR: In this paper, a systematic study has been carried out on the changes in the L-shell absorption structure of niobium as a result of changing the population of the n = 3 shell from full to having vacancies in the 3D level.
Journal ArticleDOI
The effect of line-broadening on the overall width of transition arrays in dense plasmas
D.J. Hoarty,Christopher D. B. Bentley,B.J.B. Crowley,S.J. Davidson,S.G. Gales,P. Graham,J.W.O. Harris,Carlos A. Iglesias,S.F. James,C.C. Smith +9 more
TL;DR: In this article, the effect of the plasma environment on the absorption spectrum was investigated using the HELEN laser to measure absorption spectra in the temperature range 20-60eV and density range 0.5-3g/cm3.
