The results of measurements of the differential cross section for elastic deuteron–proton scattering at the energy of 700 MeV per nucleon that were performed at the internal target station of the ...nuclotron at the Joint Institute for Nuclear Research (JINR, Dubna) are presented. These data were obtained at angles in the range between 70◦ and 120◦ in the c.m. frame. The angular dependence obtained in this way is compared with world-averaged data at similar energies and with the results of theoretical calculations performed within the relativistic theory of multiple scattering.
Neutron-diffraction methods are widely used for analyzing condensed matter, offering valuable insights into the internal structure and dynamics of the materials under study. The creation of new ...high-flux neutron sources to study promising materials and various biological systems places special demands on the operating parameters of detector systems. A new generation of position-sensitive thermal-neutron detectors should have record-breaking characteristics in terms of spatial and time resolution with a high detection efficiency. This work focuses on the exploration of new solutions for implementing detector systems in neutron-scattering stations, specifically examining the potential use and expected performance characteristics of

One of the most important activities of the IBR-2 DSC is the development of detector technologies, which will be used as a basis in designing detectors for future experiments. Detector systems ...developed by the IBR-2 DSC are described. Today they are used to good effect in research facilities or are prepared for application in the foreseeable future.
Deuteron Spin Structure (DSS) collaboration program is aimed on few nucleon correlations investigation using unpolarized and polarized deuteron beam at intermediate energy range. Data of the dp ...breakup reaction have been obtained at energy range from 300 - 500 MeV of deuteron energy for various detector configurations in region where few nucleon correlations and relativistic effects can play significant role. Results are obtained in the form of S-curve and T20 and iT11 tensor analyzing powers in case of unpolarized and polarized data, respectively. Future plans on extracted deuteron beam of Nuclotron are concerned to tensor analyzing power T20 and spin correlation Cyy of 3He(d, p)4He reaction in the kinetic energy range between 1.0 and 1.75 GeV.

A wide-aperture ring back-scattering detector for HRFD has been developed. The detector consists of six Z n S ( A g ) / 6 L i F-scintillation rings, each one of which is divided into 12 sections. Main parameters of this detector: covered solid angle 2 θ = ( 133 − 175 ) ∘ ; Ω d ≈ 2.0 sr; average absorption efficiency 85 %, geometric contribution to resolution Δ d / d < 0.0005. The concept of a detector and its data acquisition system are presented.
