The pulse parameter model of DSRD is important to improve the characteristics of the pulsed power system and reduce the complexity of the DSRD design. This article presents models for the prepulse amplitude, pulse front durations, and pulse peak based on the operating mechanism of 4H-SiC DSRD. The models establish the connection between the output pulse parameters with the DSRD structure and the material parameters. 4H-SiC DSRDs with different structures are designed for experiments, and the experimental results are consistent with the model predictions. Using the quantitative description of the pulse parameters from the proposed models, the optimization methodology is discussed to reduce the pulse front durations under the prepulse amplitude and peak pulse fixed. The accuracy of this optimization method is confirmed through simulations. The models developed in this article simplify the complex problem of nonlinear interactions involved in 4H-SiC DSRD optimization, enabling better utilization of 4H-SiC DSRD’s advantages in pulsed power systems.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 4","pages":"721-728"},"PeriodicalIF":1.3,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830573","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}

Considering that electromagnetic rail launch is a transient process, the transient inductance gradient of electromagnetic launch rail driven by different pulse current is calculated, and the time-varying effect of inductance gradient caused by current variation is studied. The results show that the transient change of pulse current in different stages will cause the transformation of rail current distribution, which affect the growth rate of the inductance gradient of electromagnetic launch rail. The inductance gradient has little change when the pulse-driven current is in the early stage of rising process and stable process, but when the pulse current is in the late stage of descent process, the faster it falls, the greater the growth rate of the inductance gradient.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 4","pages":"813-817"},"PeriodicalIF":1.3,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830470","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}

However, the mechanisms, kinetics, and disinfection doses required for bioaerosol inactivation by plasmas remain inadequately understood. In this study, we first applied optical photothermal infrared (O-PTIR) spectroscopy to examine the biological responses of bacterial aerosols to plasmas at the single-cell level. Significant carbonylation was observed in plasma-treated cells, indicating that oxidation is a crucial mechanism in bacterial aerosol inactivation. A preliminary multispecies kinetic model was proposed for bioaerosol disinfection by plasmas. By differentiating the roles of charged particles and neutral chemical species, the equivalent total chemical dose (ETCD) and equivalent total ionic dose (ETID) were introduced. ETCD primarily considers the oxidation potential of the reactive species in the plasma. The proposed model was applied to a DBD plasma-based air disinfection system and preliminarily validated. The relationship between the macroscopic dose (specific energy density, SED) and microscopic dose (ETCD) was uncovered. This study provides valuable insights into the modeling of plasma-bioaerosol interactions and the underlying mechanisms, offering a theoretical foundation for practical applications.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 4","pages":"539-552"},"PeriodicalIF":1.3,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830449","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 plasma impedance is derived by dividing the plasma potential by the plasma current. Because the time variations of the plasma potential and current differ, it is difficult to derive the time-varying phase difference. The plasma inductance is derived from the plasma potential and the time derivative of the plasma current. The plasma capacitance is derived from the plasma potential and the time integral of the plasma current, which represents plasma charge. The plasma impedance represents a capacitive load in the first half of plasma generation over time and an inductive load in the second half with the plasma bullet traveling. Consequently, when the plasma impedance is at its minimum, the reactance component is canceled out and the plasma impedance is equal to the resistance of the plasma.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 4","pages":"697-703"},"PeriodicalIF":1.3,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830533","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}

Using the pseudo-potential approach, the impact of this force on nonlinear DA waves in polarized dusty plasmas composed of inertial negative dust grains, Maxwellian electrons, and nonthermal ions is explored. The results reveal that the nonthermal charge gradient force enhances the amplitude of DA solitons, affects the dust grain charge and density profiles, and leads to increased electron depletion.

Due to the strong spatiotemporal distribution characteristics of particles, the physical and chemical properties of plasma jets can be adjusted by changing the type and ratio of working gas, which is crucial for improving jet treatment efficiency and achieving specific treatment effects. This article innovatively analyzes the variations in the spatial distribution, intensity distribution, and activation region distribution of short-lived active substances that are crucial in the application of plasma jets under different gas backgrounds. Under the context of multiple variables, the physical characteristics of the plasma jets are comprehensively analyzed.
