The strong-field sections were connected forming either uniform magnetic field (long magnetic mirrors) or the multiple-mirror configuration (the corrugation period was 22 cm, the number of corrugation periods was 13, and the corrugation depth was 1.4). The plasma flow parameters were studied using the Mach and Langmuir probes. The experiments were carried out at the electron and ion temperatures of Te ≈ 20 eV and Ti ≈ 6 eV, respectively. In the output strong-field section, the on-axis plasma density was (1–3) × 1019 m–3 at the end of the density accumulation stage and (3–5) × 1018 m–3 in the decay stage. In this case, the plasma flow along the magnetic field was generally collisional, with the free path of ions being less than the corrugation period of the magnetic field. The differences in plasma accumulation and decay processes in the central trap, plasma flow in the output strong-field section, and MHD stability of plasma in the solenoidal and the multiple-mirror configurations are discussed. Possible ways for reaching plasma parameters required for efficient operation of multiple-mirror sections are considered.","PeriodicalId":735,"journal":{"name":"Plasma Physics Reports","volume":"52 5","pages":"543 - 555"},"PeriodicalIF":1.0,"publicationDate":"2026-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148323873","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}

Then the characteristics of modulation instability for both transverse and longitudinal perturbation modes is systematically studied. It is shown that the transverse modes play a major role in the formation of nonlinear localized structures. As the non-extensive parameter increased, the growth rates of the instability increased, while the characteristic scales of density cavitons and localized field decreased. And as the non-extensive parameter (q = 1), the results of Maxwellian case will be recovered. Furthermore, it is also found that the influences of the non-extensive parameter on transverse modes’ instability are more significantly than that of longitudinal modes. Therefore, selectively injecting energetic electrons into the wake region alters the characteristics of nonlinear localized density cavitons to make the stealth space vehicle difficult to detect accurately. For potential application of spacecraft stealth technology in ionospheric and plasma environments, the present work provides a significant theoretical basis for anti-detection.","PeriodicalId":735,"journal":{"name":"Plasma Physics Reports","volume":"52 5","pages":"631 - 639"},"PeriodicalIF":1.0,"publicationDate":"2026-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148323882","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 beam is designed to enhance the parameters and improve the transverse stability of the plasma in the GOL-NB open plasma trap. The aim of the study was to estimate the fraction of the beam current reflected by the trap input magnetic mirror. The limiting beam and plasma parameters specified in the model correspond to experimental data and estimates obtained by probe and other measurements. The combined effect of the cathode surface temperature and roughness, as well as the inclination of the external and beam magnetic fields to its plane, on the angular distribution of electron velocities is considered. The calculations show that for the cathode center with the greatest roughness, almost complete beam passage into the magnetic mirror with an aspect ratio of 60 is expected; the fraction of reflected electrons obtained was approximately 1%. For the rest of the cathode surface, the fraction of reflected electrons is negligible.","PeriodicalId":735,"journal":{"name":"Plasma Physics Reports","volume":"52 5","pages":"569 - 575"},"PeriodicalIF":1.0,"publicationDate":"2026-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148323877","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}

Linear analysis of MAWs was performed and the dispersion equation was derived. The analysis performed resulted in obtaining the exact expression for the linear velocity of muon-sound waves. By means of normalizing soliton velocity to this expression, its Mach number was obtained. Nonlinear analysis was performed involving the Sagdeev pseudopotential method. It was found that in the e‒μ‒i+-plasma, the stationary periodic subsonic MAWs can propagate, as well as supersonic muon-acoustic solitons (MA-solitons). It was also found that in MAWs, the muon and electron plasma components change in antiphase with each other. It was shown that in the e‒μ‒i+-plasma, in the case of relative electron density being equal to unity or somewhat less, the Mach numbers of muon-acoustic solitons can be abnormally high. Profiles of physical parameters in such hypersonic MA-solitons were calculated.
