  Novel experiments to study fundamental properties of high-energy-density states in matter generated by intense heavy ion beams will be carried out by the HED@FAIR collaboration at FAIR. For strong transverse focusing a special final focus system consisted of four superconducting large-aperture high-gradient quadrupole magnets will be installed at the end of the HED@FAIR beam line. Design and main characteristics of the quadrupole are discussed. Stress - strain dependence of the quadrupole superconducting cable and electrical strength of the cable insulation are measured. Results of mechanical and thermal calculation of main parts of the quadrupole are presented.

  The purpose of this research was precision statistical simulation of multi-particle radiation transport using a realistic 3D model of clinical setup prototype and the systems of slot-hole collimators for on-line monitoring of Bragg-peak position at a proton therapy complex Prometheus to define of an available detecting accuracy and the choice of its optimum parameters. Numerical simulation of the experiments was carried out based on the RTS&T high-precision radiation transport software package using files of evaluated nuclear data from ENDF/B VIII.0 library. Results: To determine the error of the longitudinal Bragg peak monitoring, a series of 24 calculations was performed using different sequences of pseudo-random numbers to construct trajectories of particles in the calculation system. When using 3 slits, the RMS-error in determining the longitudinal coordinate was 1.5 mm. Keywords: radiation transport, Monte Carlo method, radiation therapy, medical accelerators, Bragg peak verification, mathematical modeling, irradiation planning, detection techniques.

  In the frame of collaboration with FAIR, the IHEP will develop and fabricate superconducting wide-aperture quadrupole magnets with the following parameters: the inner diameter of the coil is 260 mm; the integral field gradient is 66 T. The results of strength calculations of the most important components of these quadrupole magnets are presented in the article. Dependence of strains on the stresses of a superconducting cable for a quadrupole is presented. The stress-strain state of the collars is analyzed; the mechanical analysis of the helium vessel and the vacuum vessel of the superconducting quadrupole magnet is carried out.

  Over the past decade, there has been a significant update of the world's evaluated nuclear data libraries. The paper presents selected results of testing the current versions of these evaluated nuclear data libraries such as ENDF/B VII.1, ENDF/B VIII.0, ROSFOND, BROND 3.1, JENDL4.0u +, JENDL-4.0/HE, JENDL/HE 2007, CENDL 4.0, TENDL 2015, FENDL 3.0, JEFF 3.2 based on the integral experiments included in the Shielding Integral Benchmark Archive and Database (SINBAD) using the RTS&T* reference accuracy class code system. The RTS&T code uses continuous-energy nuclear and atomic evaluated data files to simulate of trajectories and discrete interactions of the particles in the energy range from thermal energy up to 20/150/3000 MeV. In current model development all data types provided by ENDF-6 format are takes account in the coupled multy-particle transport modeling. Universal data reading and preparation procedure allows to use various data file written in the ENDF-6 format. The ENDF data pre-processing (linearization, restoration of the resolved resonances, temperature dependent Doppler broadening of the cross sections and checking and correcting of angular distributions and Legendre coefficients for negative values are produced automatically with the PREPRO2017, NJOY2016, and GRUCON2017 code systems.
