The radiation emitted by the aluminum plasma was dispersed with an ultra-high resolution spectrograph (λ/Δλ≈6000). From the recorded films one can extract a set of time-integrated emission lineouts associated with the corresponding spatial region of the plasma. The observed spectra include the Lyα, Heβ, Heγ, Lyβ and Lyγ line emissions and their associated He- and Li-like satellites thus covering a photon energy range from 1700 eV to 2400 eV approximately. The data analysis rely on the ABAKO/RAPCAL computational package, which has been recently developed at the University of Las Palmas de Gran Canaria and takes into account non-equilibrium collisional-radiative atomic kinetics, Stark broadened line shapes and radiation transport calculations. | URI: | http://hdl.handle.net/10553/46054 | ISBN: | 978-0-7354-0588-2 | ISSN: | 0094-243X | DOI: | 10.1063/1.3026501 | Source: | Spectral Line Shapes Vol 15 [ISSN 0094-243X], v. 1058, p. 75-+ |
