  • Efficient approach to analysis of TM modes in coaxial gyrotron cavity with corrugated insert 
    Tkachova, T.I.; Shcherbinin, V.I.; Tkachenko, V.I. (Вопросы атомной науки и техники, 2018)
    Electromagnetic characteristics of TM modes of a coaxial gyrotron cavity with a corrugated inner conductor are investigated. Coupled-mode method based on re-expansion of the cavity fields in terms of the Gegenbauer ...
  • Eigenvalues and eigenfields of a corrugated gyrotron cavity with conducting walls 
    Tkachova, T.I.; Shcherbinin, V.I.; Tkachenko, V.I. (Вопросы атомной науки и техники, 2018)
    Electromagnetic analysis of a cylindrical gyrotron cavity with longitudinal wall corrugations is performed on the basis of the approximate surface impedance model (SIM) and the full-wave spatial harmonic method (SHM). ...
  • Features of plasma formation for SNF magnetoplasma reprocessing at ionization stage 
    Katrechko, V.V.; Yuferov, V.B.; Svichkar, A.S.; Tkachova, T.I.; Shariy, S.V.; Ilichova, V.O. (Вопросы атомной науки и техники, 2016)
    Stage ionization is an intermediate stage separation of spent nuclear fuel (SNF) between heating stage and magnetoplasma separation of fission products (FP) and nuclear fuel (NF) in rotating plasma. The process of plasma ...
  • Mode selection by ohmic losses in longitudinally corrugated cavities of sub-THz second-harmonic gyrotrons 
    Tkachova, T.I.; Shcherbinin, V.I.; Tkachenko, V.I. (Вопросы атомной науки и техники, 2019)
    Ohmic wall losses are proposed as a means for improving the mode selection in a cylindrical gyrotron cavity with longitudinal wedge-shaped corrugations. Such losses depend on mode frequency and geometrical parameters of ...
