The IBR-2M reactor plant, the complex of technological equipment and the reactor building will develop their final life depending on the operating mode in 2032-2037. One of the proposed options to replace the IBR-2M reactor is the NEPTUNE reactor (average power of 15 MW, pulse duration of 210 μs and an average neutron flux of 1,6 x 1014 n/cm2/s and at peak power of 3,8 x 1017 n/cm2/s), which...
Fast reactor cores require steels and alloys resistant to high-energy neutron fluxes and capable of maintaining sufficient medium-temperature (300-500°C) strength. EP-450 (1Cr13Мo2NbVB) ferritic-martensitic steel, containing 11-13.5% chromium, is used as an acceptable material for cladding and covers of fuel assemblies (FA) of sodium cooled fast reactors. Its competitive advantage is the high...
The previously developed non-destructive method for diagnosing heavy ion beam losses, based on neutron registration, has undergone significant optimization. The main goal of this work was to address identified issues and improve the sensitivity and reliability of the system. During the optimization process, key tasks were solved, including adjusting the operating voltages to enhance detector...
When a wave propagates in the active line of a spiral high-voltage pulse generator, the electric energy is converted into the energy of the magnetic field, and the electric energy of the coaxial capacitors connected in series. After reflection from the open ends of the line, the energy of the magnetic field in it begins to transform into electric energy, and the wave in the active line changes...
At the BINP the VEPP-5 injection complex delivers electron and positron beams through transportation channels to the VEPP-4M and VEPP-2000 colliders. There is a necessity to change magnetic field vectors in dipole magnets to deliver particles with different charges, such as positrons and electrons. Because of some physics effects, in order to achieve precise adjustment of field, it's necessary...
In the context of modern accelerator technology, it is essential to guarantee the specified characteristics of the extracted electron beam. In addition to the information regarding the energy and intensity of the beam, it is crucial to ascertain its spatial and angular distribution [1].
The position of the particle beam in space and its transverse intensity distribution can be determined by...
Electromagnetic radiation in millimetre and sub-millimetre wavelength range is a area of intense studies due to its application for longitudinal beam diagnostics and for generation of intense radiation beams. Transition radiation (TR) appearing when a fast charge particle crosses an vacuum-matter interface is one of the mechanism broadly used for this purpose, because its spectral angular...
The NICA accelerator complex (JINR) includes a Heavy ion linear accelerator (HILAC) designed for injection of heavy ions (with the mass to charge ratio A/Z ≤ 6.35) into the storage synchrotron-Booster. Commissioning sessions with accelerated Xe28+ ions showed insufficient beam intensity of the required heavy ion beam parameters for experiments in the Collider. A multiple injection technology...
