  • 3D magnetic field effects in the NSC KIPT compact intense X-ray generator 
    Zelinsky, A.; Mytsykov, A. (Вопросы атомной науки и техники, 2004)
    The new generation of intense X-rays sources based on a low-energy electron storage ring and on the Compton scattering of an intense laser beam allows to produce hard X-rays with intensity up to 10¹⁴ phot/s. One of the ...
  • Acceleration of charged particles by elliptic polarized waves of large amplitude 
    Buts, A.V.; Buts, V.A.; Kuzmin, V.V. (Вопросы атомной науки и техники, 2004)
    In this paper the results of investigations on the charged particle dynamics in the homogeneous constant magnetic field and in the field of a flat wave of arbitrary intensity are presented. When the magnetic field is absent ...
  • Characteristics of undulator-type radiation emitted by bunch of charged particles in wakefield 
    Opanasenko, A. (Вопросы атомной науки и техники, 2004)
    Characteristics of the undulator radiation, emitted by a bunch of relativistic charged particles interacting with the nonsynchronous harmonics of the transverse wakefields in a periodic structure, are presented.
  • Dynamics of heavy ions in the isochronous cyclotron for production of nuclear membranes 
    Onischenko, L.M.; Samsonov, E.V. (Вопросы атомной науки и техники, 2004)
    Isochronous cyclotron CYTRECK intended for a production of nuclear membranes was put into operation in 2002 year in Dubna. The ions with the relation A/Z=5 are accelerated to the energy ∼2.4 MeV/nucleon and extracted ...
  • Formation of localised electron flow inside an interaction region of relativistic magnetron 
    Agafonov, A.V.; Lebedev, A.N.; Krastelev, E.G. (Вопросы атомной науки и техники, 2004)
    For an increasing of the efficiency of relativistic magnetrons it is very important to prevent the axial drift of electrons away from an interaction region and the generation of a parasitic e-beam at the end of a cathode, ...
  • High-current hollow beam dynamics in RF electron guns 
    Khodak, I.V.; Kushnir, V.A.; Mitrochenko, V.V. (Вопросы атомной науки и техники, 2004)
    RF electron guns with a metal-dielectric cathode are able to generate intense beams with nanosecond current pulse duration. The plasma developed during the dielectric surface flashover in vacuum is the source of particles ...
  • Mechanisms of an electron stream self-bunching in magnetron guns 
    Gritsunov, A.V. (Вопросы атомной науки и техники, 2004)
    Various processes of self-bunching of reentrant electron cloud nearby a distributed cylindrical cathode in crossed fields are investigated theoretically using particle-in-cell (PIC) simulation algorithms. As most probable ...
  • Microwave generation by supercritical REB at plasma assistance 
    Chupikov, P.T.; Onishchenko, I.N.; Prokopenko, Yu.V.; Pushkarev, S.S.; Yegorov, A.M. (Вопросы атомной науки и техники, 2004)
    The experimental researches on generation of microwave radiation in a system with a supercritical current of a relativistic electron beam produced in the magnetically isolated diode and external plasma source are carried ...
  • Numerical simulation of 3D ion ribbon beam dynamics in RF undulator linac 
    Masunov, E.S.; Polozov, S.M (Вопросы атомной науки и техники, 2004)
    The ion ribbon beam can be bunched and accelerated in linear accelerator with RF undulator (UNDULAC-RF). The acceleration and focusing of beam are realized without using a synchronous wave in such an accelerator. The results ...
  • Numerical simulation of the supercritical electron beam dynamics in magnetic field of finite size in the presence of plasma 
    Markov, P.I.; Onishchenko, I.N.; Sotnikov, G.V. (Вопросы атомной науки и техники, 2004)
    The first results of development of a numerical electromagnetic 2.5-dimensional code «SOM 2.5» (3 dimensional by the velocities and 2 dimensional by the coordinates) for researching of a virtual cathode in the presence ...
  • Variant of alternating phase focusing with the stepped change of the synchronous phase 
    Bomko, V.A.; Kobets, A.P.; Ptukhina, Z.E.; Tishkin, S.S. (Вопросы атомной науки и техники, 2004)
    In the paper the calculation of the accelerating structure with the stepped change of the synchronous phase is presented. The method is tested for the calculation of the accelerating structure and He⁺ beam with A/q=4 in ...
