Technique for Plasma Diagnostics Based on Resonance Lines of Ne-Like Kr XXVII Ion and Its Satellites
The X-ray spectral diagnostics of laser plasma of heavy elements that does not contain few-electron ions is considered. The X-ray spectral method for measuring the temperature and density of laser plasma of krypton cluster targets is developed. It is based on analyzing resonance spectral lines of Ne-like krypton ions Kr XXVII and their two-electron satellites arising due to transitions in Na- and Mg-like Kr XXVI and Kr XXV ions. Using the results of the calculations performed, it is possible to determine the ion density of plasma in the range of 1017–1021 cm–3 and the electron temperature in the range of 200–1000 eV. It is shown that one spectrometer with the spherically curved quartz crystal, which has a sufficiently high spectral and spatial resolution, can be used for experimental recording all required diagnostic spectral lines of krypton ions.
期刊介绍：
Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
