  • 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 ...
  • Features of exciton transport in J-aggregates of amphi-PIC 
    Malyukin, Yu.V.; Sorokin, A.V.; Lebedenko, A.N.; Efimova, S.L.; Guralchuk, G.Ya. (Functional Materials, 2005)
    The experimental results concerning the efficiency of exciton migration under the exciton selective excitation within the amphi-PIC -J-aggregate absorption band at different temperatures are presented. To detect the exciton ...
  • 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 ...
  • Non-conventional operation modes for millimeter wave relativistic magnetrons 
    Gadetsky, N.P.; Lebedenko, A.N.; Magda, I.I.; Shtan’ko, A.A.; Volovenko, M.V. (Вопросы атомной науки и техники, 2016)
    The operation of 8-mm band relativistic magnetrons is considered for traditional and inverted-voltage regimes. The results obtained in a series of experiments are discussed.
