Scientific Programme:
Experimental and theoretical investigation of symmetry breaking effects in reactions with neutrons and fundamental properties of the neutron to test the parameters of the Standard Model and search for "new physics". Investigation of the properties of excited nuclei, reactions with emission of charged particles, fission physics. Obtaining of relevant data for astrophysics, nuclear power engineering and nuclear waste transmutation problem using neutron- and gamma-induced reactions. Application of neutron physics methods in other fields of science and technology. Development and construction of detectors of neutrons and other ionizing radiation, as well as applied methods in nuclear physics with neutrons. Development of the Intense REsonance Neutron Source (IREN) and the experimental base at the IREN and IBR-2 facilities. 

Expected main results in 2018:

    Applied and methodological research:
  • Calibration measurements with a 2D model of a position-sensitive detector with a resolution for X, Y coordinates of no worse than 0.7 mm. 

  • Manufacturing of the first section of the detector of multiple neutrons based on SNM-14D counters. 

  • Investigation of thin near-surface layers containing various elements with a depth resolution of about 10 nm using nuclear-physics methods (Elastic Recoil Detection Analysis and Rutherford Backscattering Spectrometry). 

  • Elemental and isotopic analysis of archaeological samples at the IREN facility using neutron spectroscopy, neutron and gamma activation analyses. 

  • Comparative analysis of elemental analysis methods using the tagged neutron method, standard neutron sources and other non-destructive methods. 

  • Carrying out of neutron activation analysis of environmental, geological, biological samples and novel materials at the IBR-2 reactor using the REGATA facility in the framework of the projects supported by grants and programs of JINR Member States and its Associated Members, RFBR and IAEA. 

  • Construction of a spectrometric system to measure natural and man-made radioactivity for radioecological and materials science research. 

  • Work on automation of neutron activation analysis in INP (Almaty, Kazakhstan). Training of INP personnel (Almaty, Kazakhstan) on the theoretical foundations of neutron activation analysis and practical application of modern software for obtaining and processing spectrometric data. 

    Development of the IREN facility
  • Providing the neutron beam time of 1000 hours from IREN for physical experiments. 

  • Installation of the cooling system of the LUE-200 accelerator.
