The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

ABSTRAKT

The paper presents the results of the OES technique to measure local parameters of inhomogeneous fluctuating plasmas using spectral line profiles in the plasma total emission. The technique does not require time-resolved recording of the emission. The plasma time behaviour is accounted for using prior observations at the necessary time resolution. Two cases have been examined: quasi-periodic and stochastic time changes of plasma temperature. Simple equations are found to obtain profile characteristics (half-widths, shifts) of a spectral line for the plasma local (in time and space) emissivity using the line spectral profile in the plasma volume emission during the observation time. The characteristics can be applied for the plasma diagnostics. An extensive numerical simulation is performed for emission spectra of the plasma volumes having different spatial distributions and time behaviour of the parameters. The results have been compared with the analytical approximations. Resulting data have confirmed the technique applicability and allowed to find limits of the technique use and possible errors.
