  • Acceleration of different ion types in single RFQ structure 
    Ovsyannikov, A.D.; Durkin, A.P.; Ovsyannikov, D.A.; Svistunov, Yu.A. (Вопросы атомной науки и техники, 2016)
    The possibility of different acceleration of hydrogen and deuterium ions in a single accelerating RFQ channel is considered. Effective capture of particles into acceleration in general case may be proved by optimization ...
  • Application of optimization techniques for RFQ design 
    Ovsyannikov, A.D.; Ovsyannikov, D.A.; Altsybeyev, V.V.; Durkin, A.P.; Papkovich, V.G. (Вопросы атомной науки и техники, 2014)
    Optimization approach to the beam dynamics optimization in RFQ accelerators is considered. A statement of the optimization problem and its solving methods are described. As an example, an optimization of 47.2 MHz RFQ ...
  • Characteristics of ADS target irradiated by 200…400 MeV proton beam 
    Svistunov, Yu.A.; Kudinovich, I.V.; Golovkina, A.G.; Ovsyannikov, D.A.; Bogdanov, A.A.; Tanchuk, A.V. (Вопросы атомной науки и техники, 2013-04-04)
    The problems of target choice for compact ADS with reactor thermal power 200…400 MW and 200…400 MeV proton beam are considered. Simulation results of neutron yield from fissile and non-fissile targets are presented and the ...
  • Mathematical methods of motion correction in radionuclide studies 
    Ovsyannikov, D.A.; Kotina, E.D.; Shirokolobov, A.Yu. (Вопросы атомной науки и техники, 2013)
    Detection and correction of patient motion during the acquisition of diagnostic data is an important step in the processing of radionuclide studies, since even a small shift of the patient’s body at this moment can affect ...
  • Mathematical optimization model for alternating-phase focusing (APF) linac 
    Ovsyannikov, D.A.; Altsybeyev, V.V. (Вопросы атомной науки и техники, 2013)
    Mathematical model of beam dynamic optimization in an equivalent traveling wave is suggested. The problem of the APF linac parameters optimization is being discussed. Beam dynamics in the 14 MeV deuteron accelerator are ...
  • Nuclear constants database for fuel isotope change estimation 
    Golovkina, A.G.; Loskutova, A.D.; Ovsyannikov, D.A. (Вопросы атомной науки и техники, 2018)
    Description of database and client program developed by the authors and designed to store, process and extract nuclear constants used in calculations of nuclear fuel isotope changes is presented. On the basis of the ...
  • Optimization of APF accelerators 
    Ovsyannikov, D.A.; Altsybeyev, V.V. (Вопросы атомной науки и техники, 2013)
    Optimization in an equivalent traveling wave of APF accelerating structures is considered. New approach to obtain synchronous phase sequence in APF structure is suggested. Space charged was taken into account in considering ...
  • Velocity field based method for data processing in radionuclide studies 
    Kotina, E.D.; Ovsyannikov, D.A. (Вопросы атомной науки и техники, 2018)
    In this paper, we consider a method of construction of a velocity field based on an optimization approach. A general formulation of the problem is given. It is shown how, under the appropriate assumption, it reduces to ...
  • Оptimization approach to the synthesis of plasma stabilization system in tokamak ITER 
    Ovsyannikov, D.A.; Zavadskiy, S.V. (Вопросы атомной науки и техники, 2018)
    Synthesis of the controller of ITER plasma stabilization system is considered. Stabilization system is based on tokamak diagnostic measurements, defines the voltages in tokamak coils and has the filtering properties. ...
