Issues addressed and main goals of research:

Regular operation, modernization and development of control systems for CM-201 and CM-202 cryogenic moderators. Development and equipping of new spectrometers, as well as modernization and reconstruction of equipment for the existing IBR-2 spectrometers in order to improve their parameters, expand experimental capabilities and ensure their faultless operation. Scientific and technical support for the development of beam-forming systems, neutron detectors, sample environment systems, cryostats and cryomagnetic systems, as well as electronics and software of data acquisition systems. Development of FLNP information and computing infrastructure.

Expected results in the current year:
  • Maintenance of regular operation of the complex of CM-201 and CM-202 cryogenic pelletized moderators for physics experiments. Automation of the vacuum system and the system for supplying helium to the pneumatic transport pipeline of the CM-202 cryogenic moderator; upgrade of software for control systems of the CM-202 moderator.

  • Investigation of radiation resistance of materials using the radiation research facility. Neutron activation analysis of irradiated samples using a high-purity germanium spectrometer.

  • Complex calculations and optimization of spectrometers. Methodological studies of neutron background conditions at IBR-2 spectrometers. Determination of sources of neutron background, its level and influence on experimental results.

  • Development of the horizontal/vertical cryostat with a superconducting magnet. Development of the available cryogenic test bench for working with liquid helium and its adaptation to produce pure high-pressure helium-3 for filling gas neutron detectors. Modernization of cryostats on neutron beams (at the requests of instrument responsibles).

  • Manufacturing, installation in the regular position and testing of 4 sectors of the BSD detector at the HRFD diffractometer (work under the BSD project). Study of a prototype of a 2D large-area (~1 m2) scintillation detector for small-angle neutron scattering experiments.

  • Equipping of the REFLEX spectrometer with a beam monitor (IBR-2 beamline 9).

  • Manufacturing of elements of the detector system for the REMUR spectrometer. The first stage of the assembly of the detector system.

  • Investigation of solid neutron converters based on boron compounds.

  • Calculation and simulation of position-sensitive counters with a resistive anode wire up to 1 m long; development of a detector electronics system.

  • Study and use of programmable logic controllers (PLC) for their application in automated control systems for actuators, choppers and current sources; development of a PLC test bench and preparation of proposals for the introduction of PLC at IBR-2 spectrometers. Development of technical specifications for software and user interface for PLC.

  • Maintenance and development of the Sonix+ software package at the request of users and in order to improve the internal structure. Upgrade of Sonix+ for the available spectrometers and its installation at new IBR-2 spectrometers.

  • Modernization of the FLNP mail system. Development of Wi-Fi network in FLNP buildings. Creation of a server segment of the network with a rate of 10 Gbit/s.
