DESCRIPTION:Speakers: Mikhail Kirsanov (MEPhI)\nThe study of nuclear fusio
 n reactions involving light nuclei in crystalline structures is a signific
 ant topic for both fundamental research and practical applications. Experi
 mental studies have demonstrated that the processes of deuterium nuclear f
 usion in solid and gaseous targets differ significantly. A number of exper
 imental results have been obtained\, indicating the possibility of reducin
 g the energy required to initiate nuclear reactions in solids due to the e
 ffects of hydrogen interaction with the crystal lattice. \nUsing the HELIS
  ion accelerator (Lebedev Physical Institute of the Russian Academy of Sci
 ences\, Moscow)\, we conducted a series of experiments to investigate d+d 
 nuclear reactions in various crystalline structures. The energy of the deu
 terium ions varied from 10 to 45 keV\, and the beam current ranged from 20
  to 100 μA. Scintillation detectors with organic crystals were used to re
 gister the neutrons produced in the deuterium fusion reactions. \nThis pap
 er presents the results of experiments on studying d+d reactions in Pt and
  Ti metal targets\, as well as in polycrystalline CVD diamond. For the fir
 st time\, similar experiments were carried out with a B4C ceramic target. 
 The neutron yield from these targets was measured as a function of irradia
 tion time\, deuterium ion beam parameters\, and target temperature. \nA si
 mulation of the passage of deuterium ions through the substance of the spe
 cified targets was carried out. Based on experimental data and the modelin
 g results\, deuterium concentrations in Pt\, Ti\, CVD diamond\, and B4C we
 re calculated as functions of irradiation time\, beam current\, deuterium 
 ion energy\, and target temperature. \nThe obtained results are presented 
 in the report.\n\nhttps://indico.particle.mephi.ru/event/626/contributions
