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

摘要

In this work a 2D model for simulating an applied-field magnetoplasmadynamic (AF-MPD) thruster with a hollow cathode made of thoriated tungsten was constructed using Comsol Multiphysics. The model allowed for self-consistent description of plasma processes inside an ionization chamber in the thruster and heating of the cathode due to ion bombardment. The distribution of such discharge parameters as charged and excited particle densities, charged particles' mean energies and temperatures, gas temperature, cathode temperature, and electric potential were obtained. Numerical experiments were carried out for different geometries and optimal configuration of AFMPD thruster with a hollow cathode was obtained.
