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

This work shows the experimental characterization of a helium atmospheric pressure microwave plasma produced by the Axial Injection Torch (TIA design) at 2.45 GHz. The axial and radial description of the discharge is made under different microwave power and gas flow-rate conditions. For that, the electron and gas temperature and the electron density are determined by using optical spectroscopic diagnostics. The flame produced by the TIA is a non-thermal plasma, which is characterized by electrons with kinetic energies that are much higher than those of the ions, atoms or molecules. Since features of departure from Saha-Boltzmann equilibrium are detected, the possible deviation from equilibrium has been taken into account in order to interpret the results correctly. Specifically, spectroscopic measurements combined with theoretical results obtained by a collisional radiative model were used to determine the radial distribution of the electron temperature and electron density in the flame. As the TIA produces a free expanding plasma, species from the surrounding air enter the discharge. Therefore, a preliminary study of the role of the molecules incoming in the plasma is presented.
