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

A combined experimental/modeling approach has been taken in order to further our understanding of the high-pressure sulfur discharge. This plasma has the appealing property of producing a pleasant visible spectrum and doing so efficiently. Moreover, the spectrum originates entirely from the sulfur dimer. However, very little is known about this new visible light source.
The integrated environment for the construction and execution of plasma models, PLASIMO [1], has been used to model a 1D LTE energy balance of the lamp including radiation transport with the aim of reproducing the observed spectrum [2, 3, 4] Several atomic lines found in the spectrum were used for the direct measurement of temperature [5]. Power interruption experiments were performed and the spectral response was both measured and modeled as a function of wavelength [6].
The LTE model reproduces measured spectra and operational trends well. Average plasma temperatures of 4000 K have been measured and the model is within 10% of this value. The response of the entire spectrum to power interruption also agrees well with measurement. We have found that while the BX transition in S2 is the solely responsible for the spectrum, the presence of S3 is critical to the understanding of the discharge.
