X-Ray Spectroscopy of Highly Charged Ions in Laboratory and Astrophysical Plasmas

摘要: The Universe is rich with X-ray sources which can now be observed unprecedented resolution using instruments on Chandra and XMM-Newton. In order to interpret their spectral signatures derive reliable information regarding the physical characteristics dynamics of these objects environments, detailed models have been developed require vast amounts highly accurate data atomic collisional radiative properties for ions in a broad range ionization states. These are usually obtained from theoretical calculations through large parameter space conditions such as temperature density explored. Critical reliability careful benchmarking theoretically generated high-precision laboratory measurements. To provide picture astrophysics, goal develop set key spectroscopic diagnostics an accuracy ( ∼ 5–10%) that commensurate uncertainties highest quality astrophysical spectra. Using band, high microcalorimeter coupled EBIT, we studying behavior charged plasma ions. Our goals achievable some our results presented here. A new technique improving measurement also described.
