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

要約

The investigations of the powerful electric discharge in high density hydrogen were continued in IPE RAS. In these experiments the influence of discharge current magnitude, current rise rate and initial particle density on arc temperature was investigated. These experiments were performed under the following conditions: charge voltage of the capacitive energy supply — 8.0−14.0 kV, stored energy — 140−450 kJ, discharge current — 200−600 kA, current rise rate — 109−1010 A/s. The maximum particle density nmax, achieved just before the discharge was about 2.0×1022 cm−3. Arc temperature was calculated on the basis of measured electric parameters of arc and bright temperature of its outer layer.
It was revealed that increasing in initial particle density, discharge current magnitude and current rise rate leads to the reducing of arc diameter that results in increasing of temperature of the discharge channel. Obtained experimental data permits to define the main parameters of the discharge: temperature of arc channel, plasma conductivity and density of charged particles in the arc channel. It was estimated that temperature of arc central zone is achieved 3×105 K at the specified initial conditions.
