  • A relativistic magnetron-type source of nanosecond-length pulsed radiation in the 8 mm waveband 
    Gadetsky, N.P.; Lebedenko, A.N.; Magda, I.I.; Melezhik, O.G.; Shtanko, A.A.; Volovenko, M.V. (Вопросы атомной науки и техники, 2017)
    The paper describes an up-graded facility for studying performance of a high voltage pulsed magnetron of the 8 mm operation waveband. A pulse forming driving source of high output impedance is offered, yielding voltage ...
  • Excitation of oscillations in the vircator with premodulation 
    Melezhik, O.G.; Pashchenko, A.V.; Romanov, S.S.; Shapoval, I.M. (Вопросы атомной науки и техники, 2014)
    The electronics flows dynamic in vircator premodulation diode has been studied. The problem on stationary states and disturbances in the first order approximation of interacting contrary flows-direct and reflected from ...
  • High-frequency properties of the electron flow slowing down in a planar diode

    The instability of the electron flow injected into a planar diode and slowed down in it under the action of the external electric field is investigated through the exact solution of the set of inhomogeneous hydrodynamic ...
  • Millimeter-wavelength relativistic magnetron: problems of microwave power extraction 
    Gadetski, N.P.; Korenev, V.G.; Lebedenko, A.N.; Magda, I.I.; Melezhik, O.G.; Sinitsin, V.G.; Shtanko, A.A.; Volovenko, N.V. (Вопросы атомной науки и техники, 2021)
    The relativistic magnetrons operating at millimeter wavelengths demonstrate problems with microwave power extraction, both in the radial and in axial direction. The preferred axial extraction concept can be implemented ...
  • Modification of the pierce instability of the electron flow in a diode with an external electromagnetic action 
    Melezhik, O.G.; Pashchenko, A.V.; Romanov, S.S.; Shapoval, I.M. (Вопросы атомной науки и техники, 2014)
    The stability of electron fiow passage through the diode with a neutralized space charge has been investigated on the basis of the first-order approximation for hydrodynamic and Maxwell equations. Classification of solutions ...
