  • Radioecology monitoring system for mountine areas of the Tisza river basin (Transcarpathia, Ukraine) 
    Symkanich, O.I.; Svatiuk, N.I.; Maslyuk, V.T.; Glukh, O.S.; Sukharev, S.N.; Sherehiy, A.A. (Problems of Atomic Science and Technology, 2023)
    Regularities of distribution, migration and accumulation of natural gamma-active nuclides ⁴⁰K, series of uranium ²³⁸U (²¹⁴Pb, ²¹⁴Bi) and thorium ²³²Th (²¹²Pb, ²¹²Bi, ²²⁸Ac, ²⁰⁸Tl), as well as technogenic ¹³⁷Cs in the bottom ...
  • Scintillation characteristics of heavily doped CsI:Tl, IO₃ crystals 
    Shpilinskaya, A.L.; Кudin, A.M.; Trefilova, L.N.; Zosim, D.J. (Вопросы атомной науки и техники, 2019)
    The effect of IO⁻₃ ions on spectrometric characteristic of CsI:Tl crystal has been considered. It has been shown that co-doping of CsI:Tl crystal by IO⁻₃ anions permits to obtain clear ingots with increased thallium ...
  • Secondary electron emission induced by α-particles from Mg-MgO layers 
    Zhurenko, V.P.; Kononenko, S.I.; Mahotka, I.S.; Kalantaryan, O.V.; Mysiura, I.M.; Avotin, S.S.; Rokhmanov, N.Ya. (Вопросы атомной науки и техники, 2019)
    The paper presents the results of experimental study of forward and backward electron emission induced by α- particles from the deposited film of magnesium. It was shown that during the deposition of magnesium in residual ...
  • Source of drops-free plasma flows of monocristaline zirconium 
    Borisenko, A.G.; Kostin, E.G.; Rokytskyi, O.A.; Fedorovich, O.A. (Вопросы атомной науки и техники, 2019)
    In experiments, the characteristics of a non-self-sustained arc discharge in pure vapors of monocrystalline zirconium were investigated. The minimum ignition power of the discharge in zirconium vapor was determined for ...
  • Temperature dynamics of the microdroplet fraction of metal plasma in plasma-optical devices with fast electrons 
    Goncharov, A.A.; Litovko, I.V.; Ryabtsev, A.V. (Problems of Atomic Science and Technology, 2023)
    The computer simulation of a plasma filter with fast electrons shows that the main source of droplet heating is thermal electrons, while the role of fast electrons is reduced mainly to transferring energy to slow electrons. ...
  • The physico-topological simulation of a transmission X-ray tube with induction heating of the cathode 
    Maikut, S.O.; Kuzmichev, A.I.; Tsybulskyi, L.Yu.; Shynkarenko, N.V. (Problems of Atomic Science and Technology, 2023)
    Physico-topological simulation of a transmission X-ray tube (TRT) with inductionally heated thermionic cathode is presented, taking into account physical properties of functional elements and their design. Modeling is based ...
  • The simulation of emergency action on construction materials by high current relativistic electron beams 
    Donets, S.E.; Bryukhovetsky, V.V.; Lytvynenko, V.V.; Kasatkin, Yu.A.; Startsev, О.А.; Lonin, Yu.F.; Ponomarev, A.G.; Uvarov, V.T. (Problems of Atomic Science and Technology, 2023)
    Development of many innovative areas in energy, mechanical engineering, aircraft building and other industries is limited by the strength of materials under the action of temperature gradients. In this regard, the problem ...
  • Uragan-2M gas mixing system 
    Lozin, A.V.; Kovtun, Yu.V.; Moiseenko, V.E.; Maznichenko, S.M.; Baron, D.I.; Kozulya, M.M.; Krasyuk, A.Yu.; Listopad, V.M.; Gribanov, V.Yu.; Martseniuk, Yu.P. (Вопросы атомной науки и техники, 2021)
    Gas mixture system (GMS) was developed, created and installed at Uragan-2M (U-2M) device. GMS is based on already known gas mixing method - successive puffing. It is implemented through successive puffing of several gases ...
  • Voltage source up to 30 kV with pulsation not more than 0.1% 
    Krivonosov, G.A.; Svystunov, O.А.; Vasiliev, A.V.; Sotnikov, G.V. (Problems of Atomic Science and Technology, 2023)
    A DC source with a voltage of 30 kV with a ripple of less than 0.1% has been developed and manufactured for accelerating and focusing electrons in a dielectric laser accelerator on a chip structure. The source, which has ...
