Based on the discharge voltage and current, the energy supplied by the driving pulse generator for plasma formation was investigated. It is shown that at argon pressures ≥10–3 Torr, the fraction of energy spent on plasma formation increases significantly due to the growth of the discharge current. The elemental composition of the plasma was examined by optical emission spectroscopy, and the electron temperature and density were determined from analysis of Ar II ion spectral lines, taking into account the optical thin condition of the plasma and the McWhirter criterion. Local thermodynamic equilibrium in the plasma is achieved at argon pressures ≥10–3 Torr. The dependence of the electron temperature and density on argon pressure has been determined. As the argon pressure increases, the electron temperature rises from 0.8 to 1.2  eV, while the electron density reaches (2‒5) × 1015 cm–3. The concentration ratio of argon ions Ar II to Ba II and Ti II ions in the plasma has been determined over the studied pressure range.","PeriodicalId":735,"journal":{"name":"Plasma Physics Reports","volume":"52 9","pages":"1275 - 1284"},"PeriodicalIF":1.0,"publicationDate":"2026-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1134/S1063780X26601112.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149067999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study the streamer dynamics in detail, a series of numerical experiments are being conducted in this work. The computational algorithm is based on a drift–diffusion model, in which the photoionization term is calculated in two ways: using an integral model (the Zheleznyak approach) and a differential model (a set of Helmholtz equations). The problems are solved in an axisymmetric setting in a cylindrical coordinate system on a uniform Cartesian grid. A constant potential difference of 25 kV is applied to plane circular electrodes with the radius of ({l_r} = 0.2;{text{cm}}) located at a distance of ({l_z} = 0.5;{text{cm}}). The interelectrode gap is filled with nitrogen under normal conditions with a small oxygen admixture of 0.05%. In all problems, the results obtained using both photoionization models are compared (the closeness of the solutions found is noted). The photoionization process is studied by the example of a cathode-directed streamer, and the photoionization and impact ionization rates are analyzed by simulating a two-headed streamer. The dynamics of a cylindrical discharge initiated at the anode from a ring of quasi-neutral plasma is studied.","PeriodicalId":735,"journal":{"name":"Plasma Physics Reports","volume":"52 9","pages":"1238 - 1258"},"PeriodicalIF":1.0,"publicationDate":"2026-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149068020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influence of gas heating on helium discharge characteristics was investigated experimentally and using a one-dimensional fluid model. Experimental study examines the visible light emission of a helium DBD lamp and evaluates the effects of applied voltage and frequency to optimize performance as an eco-friendly lighting alternative. The developed lamp is an efficient, mercury-free light source capable of replacing incandescent, fluorescent, and certain LED lamps that may contain toxic or heavy metals. The gas temperature evolution in the DBD discharge was determined using the heat conduction equation. To account for Joule heating, the heat transport equation was solved along the discharge gap distance. Coupling a 1D fluid model with the thermal conduction equation allowed us to calculate the temperature profile of the helium gas in the DBD discharge. We analyzed a DBD excited helium lamp under controlled conditions of 200 mbar pressure, 1500 to 2000 V sinusoidal voltages, and 20 to 50 kHz frequencies. The visible light intensity increases with applied voltage. Electrical measurements confirmed that the discharge operates in a homogeneous glow mode under optimal conditions. The plasma emission is due to the electronic relaxation of excited helium atoms and collisions with residual impurities such as oxygen. Helium’s ionization energy enables cold plasma generation, which reduces thermal effects and material degradation.","PeriodicalId":735,"journal":{"name":"Plasma Physics Reports","volume":"52 9","pages":"1285 - 1295"},"PeriodicalIF":1.0,"publicationDate":"2026-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149068007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper examines the presence of an intense continuous spectrum in the radiation of such a plasma, the shape of which is similar to the Planck spectrum. It has been shown that the source of this radiation can be carbon nanoparticles, hypothetically present in the plasma volume. The temperature of the particles in the center of the plasma, estimated from the position of the maximum of the continuous spectrum, turned out to be about 2600 K, which, within the error limits, coincides with the gas temperature. Spatial measurements of both temperatures showed that the particles are in local thermodynamic equilibrium with the gas throughout the plasma volume. The spatial temperature profile of the particles shows a uniform zone with a radius of about 1 cm in the center of the discharge, the boundaries of which correspond to the region of uniform growth of the diamond film, both in thickness and in structure. The relationship between continuous emission of carbon particles in plasma and the homogeneity of growth conditions opens the possibility of using near-infrared spectroscopy for real-time monitoring of key parameters of the deposition process, which can be used to improve the reproducibility of the synthesis of high-quality diamond films.","PeriodicalId":735,"journal":{"name":"Plasma Physics Reports","volume":"52 9","pages":"1259 - 1274"},"PeriodicalIF":1.0,"publicationDate":"2026-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149068016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
