The possibility of creating a FEM of this type in the W band on the basis of the U-2 accelerator, which forms a sheet electron beam with a cross section of 1×140 cm, is studied within the framework of the quasioptical model. It is shown that in the proposed scheme, the input Bragg 3D reflector implementing the mechanism of the three-dimensional distributed feedback allows one to ensure the synchronization of radiation along both transverse coordinates at the cross-sectional sizes of the system from tens to hundreds of wavelengths, while a small reflection from the output conventional 1D Bragg reflector is sufficient to complete the feedback loop and provide the single-mode generation regime with a high efficiency and a low ohmic-loss level. At the optimal parameters, the possibility is demonstrated of obtaining a stable narrow-band generation regime in the developed FEM with an electron efficiency of about 18–20% and a record-breaking output radiation power of up to 20 GW.</p>","PeriodicalId":748,"journal":{"name":"Radiophysics and Quantum Electronics","volume":"67 11-12","pages":"875 - 883"},"PeriodicalIF":0.7,"publicationDate":"2025-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145665919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
