Considering the randomness of space discharge, adopting a multineedle electrode structure will be more controllable and effective, and its electrical behavior needs to be analyzed in the design of the driving power supply. This article studies the load characteristics of DBD using multineedle coaxial cylindrical electrodes based on the state plane analysis method and points out the variations in power and resonance characteristics under different operating situations. It provides a foundation for the design of discharge arrays and driving power supplies. First, the reactor’s construction and the driving converter’s operation were introduced, and the state plane modeling was done with parasitic capacitance taken into account. Then, a DBD platform was built for experimental verification, depicting the working mode of a single discharge load from multiple perspectives. The difference between the ideal model and the state trajectory of a single discharge load was theoretically analyzed. Finally, comparative experiments on the load characteristics of arrays with varying discharge unit counts were carried out. The connection between power, resonant characteristics, and load scale is shown in the experimental data.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 4","pages":"661-668"},"PeriodicalIF":1.3,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830474","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}

Understanding how to adjust the impedance value of the discharge circuit is crucial for achieving a more stable and efficient discharge process, which holds significant engineering significance. In order to investigate the variation trends of impedance characteristics of the plasma channel under different discharge conditions, this study independently developed a needle-needle electrode high-voltage discharge system in water. This study measured relevant electrical parameters such as voltage and current of the plasma channel, and using circuit formulas and the particle swarm optimization (PSO) algorithm, the impedance variations of these five cycles under different discharge conditions were investigated. Circuit formulas and the PSO algorithm were usedto investigate the impedance variations of these five cycles under different discharge conditions. The results indicate that, under the experimental conditions of this study, the impedance values across the five cycles exhibit an increasing trend. When the voltage amplitude increases, the resistance of the plasma channel shows a decreasing trend; when the pressure level increases, the resistance of the plasma channel shows an increasing trend; and when the electrode gap increases, the resistance of the plasma channel also exhibits an increasing trend. Additionally, this study simulated the corresponding oscillating waveform based on the plasma impedance values and voltage formulas. By comparing the fitting degree between the actual waveform and simulated waveform, the calculated impedance characteristics obtained in this study were, furthermore, validated as reasonable.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 4","pages":"770-779"},"PeriodicalIF":1.3,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830572","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}

To investigate the air discharge mechanisms of onboard equipment under high-frequency voltage, this study analyzes the air discharge phenomena in a needle-plate gap under pulsed electric fields in high-altitude environments. The research considers factors such as temperature and air pressure at different altitudes, pulsed electric field parameters, and humidity. A simulation model of needle-plate electrode streamer discharge was constructed, and an experimental platform was developed for qualitative analysis. The results indicate that the streamer discharge characteristics obtained from simulations and experiments are highly consistent under variations in altitude, pulsed electric field parameters, and humidity. When the reduced field strength remains constant, the breakdown voltage values at different altitudes were quantitatively calculated. In addition, the effects of altitude, pulsed electric field parameters, and humidity on streamer discharge characteristics were studied. Furthermore, the study explains the underlying reasons for variations in electron density, electric field intensity distribution, and streamer development speed under different conditions.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 4","pages":"600-613"},"PeriodicalIF":1.3,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830530","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}

At relatively low plasma densities, around <inline-formula> <tex-math>$ {mathrm {e18~text {c}text {m} }}^{-3}$ </tex-math></inline-formula>, the self-injected electrons continue to move on separate trajectories inside the bubble creating well-defined electron filaments when a large bubble closes its rear edges from behind, making an angle larger than 180° measured from the interior of the bubble. At higher plasma densities, above 2.5 × 10<sup>18</sup> cm<sup>−3</sup>, the bubble closes at its rear with the edges making a smaller angle than 180°, resulting in a different injection dynamics. We examine these trajectories using Hamiltonian mechanics and how they impact the betatron oscillations in these cases. The results indicate that higher plasma densities result in smaller betatron oscillation amplitudes and larger wiggler strength parameter due to the stronger accelerating fields in the bubble, which accelerate the electrons to higher energies, giving higher Lorentz factors. We also show that by introducing a linear density upramp at the beam entrance, the bubble’s geometry is modified, thereby influencing the betatron oscillations and potentially tuning the acceleration process.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 4","pages":"780-787"},"PeriodicalIF":1.3,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830571","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}

It is shown that the common-mode (CM) capacitive current from the isolating transformer of the TWT’s depressed collector power supply passes through the output of the TWT’s cathode power supply. Therefore, an additional ripple is generated at the output of the cathode power supply. In high-voltage applications, adding filters to reduce ripple conflicts with the protection considerations of the load and the power supply. This study focuses on reducing this extra voltage ripple without adding new filters. An analysis is presented to demonstrate the relationship between the voltage ripple of the TWT’s cathode power supply and the stray capacitances of the isolating transformer. A transformer winding structure is then proposed to eliminate the CM capacitive current of the collector power supply. Simulation and experimental results show that using the proposed transformer winding structure leads to a 90% voltage ripple amplitude reduction at the cathode power supply output.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 4","pages":"713-720"},"PeriodicalIF":1.3,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830554","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 converter features a dimpled wall launcher and employs a two-stage perturbation method based on coupled mode theory, complemented by a specialized mirror system. MATLAB code was developed to analyze the electromagnetic field in the launcher wall. The radiation field emitted by the launcher is evaluated in free space, and the mirror system consists of a quasi-elliptical mirror, an elliptical mirror, and a parabolic mirror to ensure effective phase correction Through optimization of the radius, perturbation amplitude, and perturbation length, we successfully achieved efficient mode conversion and beam shaping within a compact 95-mm design. Comprehensive simulations using FEKO confirmed that this shortened launcher maintains high mode purity and low loss. Remarkably, its length is significantly shorter than other existing models and typical theoretical estimates, highlighting the effectiveness of parameter optimization in developing compact, high-performance launchers. The results indicate that the total length of the launcher is only 95 mm, with a cut length of 17 mm, comprising 17.8% of the total launcher length. Simulation findings reveal that, following phase correction, the scalar Gaussian mode content and vector Gaussian mode content at the output window reach 99.3% and 98.4%, respectively.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 4","pages":"834-841"},"PeriodicalIF":1.3,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830473","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}
