So far, the relationship between the space charge limited current (SCLC) and the cathode structure for thermionic emission mesh cathode diode has not been reported. In this article, we develop a calculation expression of the SCLC for the mesh cathode coaxial cylindrical diode, which is based on the calculation model of the helical cathode. The results show that the calculated values are in excellent agreement with the simulated values based on CST Particle Studio. In addition, we study the dependence of the SCLC of the mesh cathode diode with the change of the cathode height, radius of the cathode filament, anode voltage, and density of the mesh. It is helpful for the optimization of the cathode structure design of vacuum tubes and microwave tubes with the coaxial cylinder mesh cathode structure.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"51 9","pages":"2647-2651"},"PeriodicalIF":1.5,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41228313","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 proposed structure is an all-metallic MTM slow wave structure (MSWS) which comprises of a number of broadside-coupled split ring resonator (BC-SRR) pairs, arranged periodically in the axial direction and repeated azimuthally. Each pair of oppositely oriented split ring resonator (SRR) provides negative $mu$ and the cylindrical waveguide generates negative $varepsilon$ medium for below cutoff TE-modes propagation. The full wave cold simulation analysis of the proposed structure, using computer simulation technique (CST)-microwave studio, has been carried out with the objectives of double-negative medium (DNM) optimization, dispersion, and interaction characterization, and S-parameter validation. For the particle-in-cell (PIC) simulation analysis, the CST-particle studio (CST-PS) has been used. In this work, we report an operation of the proposed MTM-loaded BWO (MTM-BWO) employing a beam potential and total beam current of 340 kV and 1.2 kA, respectively, generating an output power of 175 MW within 22–24 ns with an efficiency of 43% using the four-beam MSWS.

The plasma system is assumed to contain hot trapped electrons following vortex-like Schamel distribution function, warm ions, and positively charged dust (PCD) species. The linear dispersion relation for the MIA wave has been obtained. The Korteweg–de Vries (K-dV), such as Schamel equation (also known as modified K-dV equation) and modified Burgers equation, has been derived by employing the reductive perturbation method along with their corresponding solutions, which enable us to study the waves analytically and numerically. The basic features (amplitude, width, speed, polarity, and obliqueness) of ion-acoustic nonlinear waves are found to be significantly modified by different plasma parameters and are discussed briefly. The considered plasma system supports compressive solitary and shock waves only. The presence of hot trapped electrons, PCD, and warm ions raises the wave amplitude, whereas the inclusion of an external magnetic field widens the wave. The increasing viscosity of a medium broadens the wave. The findings of this investigation may be implied in interpreting various nonlinear phenomena formed in many space environments, such as aurora and Saturn’s rings, and laboratory devices, such as tokamaks.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"51 9","pages":"2705-2716"},"PeriodicalIF":1.5,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41228276","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}

In order to judge whether the electrical contact state of the armature-rail is good and whether there is a transition during the launch process, this article proposes a theoretical analysis model of the armature-rail contact force considering the stiffness change of the armature arm after wear, and the nodal force and nodal temperature are extracted through finite element multiphysics coupling and mapped to the structural field with Johnson-Cook material damage failure for dynamic calculation of armature arm wear and armature-rail contact force. The simulation results show that the wear state of the armature arm, the change rule of armature wear mass, the velocity of armature after wear, and the change of armature-rail contact force after wear are consistent with the launch experimental phenomenon and the measured data, which verifies the accuracy of the finite element model for calculating the wear amount and armature-rail contact force. On this basis, the effects of different armature arm tail interference and different peak-to-average current waveforms on armature arm wear and armature-rail contact characteristics are considered. The simulation results show that the contact force curve of the armature-rail after considering wear is above the contact force curve required by the “10 N/kA” principle, and it can be considered that the armature-rail contact state is good. The calculation model of armature arm wear and armature-rail contact force established in this article can be used in the subsequent optimization design of C-shaped solid armature.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"51 9","pages":"2726-2735"},"PeriodicalIF":1.5,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41228095","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}

Previous studies in recent years have shown that terahertz (THz) communication is a potential solution to the blackout problem. Most previous studies consider the plasma sheath surrounding the reentry vehicle as a static plasma layer, although the plasma sheath always keeps evolving. In such a case, the impact of time-varying and inhomogeneous plasma distribution on the performance of vehicle antennas was rarely investigated. In this study, a plasma sheath evolution model for reentry vehicles was developed, and the evolution of the plasma sheath was obtained via numerical solution. In addition, a THz array antenna was introduced in order to investigate the effect of time-varying plasma sheath on antenna performance. The results indicate that during the reentry process of the vehicle, the antenna gain, antenna directivity, and antenna return loss vary dynamically and drastically. The performance of the onboard antenna during the reentry process is unstable, which affects the performance of the vehicle communication system. Finally, the mechanism of antenna performance variation is analyzed, and the corresponding optimization scheme to ensure the antenna performance in the plasma sheath is discussed. The present study is helpful in understanding the complexity of electromagnetic propagation in a self-consistently changing reentry plasma sheath.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"51 9","pages":"2736-2741"},"PeriodicalIF":1.5,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41228098","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}
