- ПубликацияТолько метаданныеSimulation of Ion Paths in the Target Material for the Injection Complex of the BELA Facility(2019) Ziiatdinova, A. V.; Fedin, P. A.; Nikitin, A. A.; Rogozhkin, S. V.; Kulevoy, T. V.; Федин, Петр Алексеевич; Никитин, Александр Александрович; Рогожкин, Сергей Васильевич; Кулевой, Тимур Вячеславович© 2019, Pleiades Publishing, Ltd.To realize the simulation experiments with the use of two ion beams at the injection complex of the BELA accelerator (Based on ECR ion source Linear Accelerator), it is necessary to determine the energy and irradiation angle of the beam of light ions which will be implanted into the region of radiation damage induced by heavy-ion beam. The depth of light-ion implantation is determined by the energy and kind of particles initiating the damage, as well as by their incidence angle. It is supposed that the incidence direction of heavy ions will coincide with the normal to the specimen surface. In our work, the necessary implantation zone for the iron ion beam with an energy of 3.2 MeV is located at depths of 300–800 nm. The simulation of the hydrogen and helium ion paths in the material of the iron target in the energy range from 150 to 600 keV at the angle to the normal from 0° to 65° is performed. The range of energies and irradiation angles for the hydrogen and helium ions are determined for the implantation into the radiation-induced defect-formation zone.
- ПубликацияТолько метаданныеUse of MeV energy ion accelerators to simulate the neutron damage in fusion reactor materials(2019) Spitsyn, A. V.; Bobyr, N. P.; Semennikov, A. I.; Stolbunov, V. S.; Kulevoy, T. V.; Fedin, P. A.; Кулевой, Тимур Вячеславович; Федин, Петр Алексеевич© 2019 Elsevier B.V. This paper describes experimental techniques for irradiation of fusion reactor materials with MeV energy ions. The studies were conducted at the NRC “Kurchatov Institute” – ITEP. Two MeV-range linear ion accelerators were used for sample irradiation: the Heavy Ion Prototype (HIPr) accelerator with heavy ions and I-2 accelerator with protons. Target chambers of HIPr accelerator were modified to provide the simultaneous irradiation of four 10 × 10 mm 2 samples at controlled elevated temperatures. Damage rates and profiles were calculated using the SRIM code. HIPr accelerator provided the damage of tungsten samples with 5.6 MeV Fe 2+ ions at a rate of 0.05 dpa/h. I-2 accelerator was used to irradiate tungsten samples with 22 MeV protons to create a uniform damage profile at a depth of 0–400 μm with a rate of 5 × 10 −7 dpa/h. Irradiation of tungsten samples with high energy protons causes generation of 183 Re and 184 Re with a half-life period of 70 and 38 days, respectively. Thus, the samples irradiated with a proton fluence of up to 10 20 protons/m 2 are subject to one year aging before manual handling.
- ПубликацияОткрытый доступControl and diagnostic systems for specialized synchrotron radiation source of 4th generation SSRS-4(2019) Liakin, D.; Blagov, A.; Senin, R.; Sitnikov, A.; Kulevoy, T.; Tishchenko, A.; Fedin, P.; Khabibullina, E.; Ziiatdinova, A.; Sergeeva, D. .; Ponomarenko, A.; Кулевой, Тимур Вячеславович; Тищенко, Алексей Александрович; Федин, Петр Алексеевич; Сергеева, Дарья Юрьевна© Published under licence by IOP Publishing Ltd.The general layout for Specialized Synchrotron Radiation Source 4th generation SSRS 4 is under development by leading of National Research Center "Kurchatov institute". In the framework of a collaborative project with European Synchrotron Radiation Facility (ESRF) supported by the Ministry of Education and Science of the Russian Federation, the applied research on determination of the configuration and key technical parameters for the control and beam diagnostic systems for 4th generation Specialized Synchrotron Radiation Source - SSRS- 4 is going on. The preliminary view of the proposed control and diagnostic system is presented and discussed. SSRS-4 inherits the experience of the scientific community including a great ESRF expertise in control system development (as founder of TANGO), robust diagnostics and long operational experience on ESRF's accelerator.
