Participating countries and international organizations:
Argentine, Belarus, Bulgaria, Czech Republic, Germany, Hungary, Republic of Korea, Romania, Russia, Sweden, Switzerland, Ukraine, United Kingdom, Uzbekistan.
Issues addressed and main goals of research:
Development and construction of a control system of the cryogenic moderator CM-201 for IBR-2 reactor beams N 1, 4, 5, 6, 9.
Design of equipment, electronics and software for the complex of IBR-2 spectrometers.
Development of the FLNP information and computing infrastructure according to the needs of the Laboratory
and the development strategy of the JINR computer network.
Expected results in the current year:
- Trial operation of CM-201 and CM-202 moderators for beamlines 1, 4
11 of the IBR-2 reactor. Obtaining spectra for some beamlines during operation
of CM-201 in the cryogenic mode, comparing them with spectra obtained from the thermal moderator. Automation of control over vacuum equipment
of the moderators’ complex. Test operation of the optical sensor designed to control the movement of pellets and count them during their pneumatic
transportation to the moderator chamber and of the diaphragm flowmeter of the moderators’ complex. Determination of release of radiolytic hydrogen
in the CM-201 moderator chamber.
- Investigation of radiation resistance of materials at the radiation research facility. Integration of a robotic manipulator into the video
surveillance and distance measurement system for remote control of handling samples by personnel working in high ionizing radiation fields.
- Creation of virtual models of spectrometers and simulation of neutron scattering experiments. Determination of configurations of existing and
planned neutron instruments in order to maximize beam time efficiency.
- Completion of development and manufacturing of a horizontal/vertical cryostat with a superconducting magnet and variable temperature range
of 4-300 K (PTH project), its testing and preparation for commissioning on the DN-12 diffractometer. Study of a continuous-flow cryostat based
on a closed-cycle cryocooler in various operating modes. Modernization of cryostats, cryogenic and vacuum equipment of IBR-2 spectrometers
(by request of instrument responsibles).
- Completion of work under the BSD project (completion of manufacturing, assembling and tuning of the first sector of the BSD detector
for the HRFD diffractometer).
- Development of a detector system based on 2D PSD with a central opening for a direct beam on the REMUR spectrometer (development of technical
design, purchase of components and electronic modules, manufacturing of necessary parts and components). Improvement of technologies for manufacturing
gas detectors (tuning and commissioning of winding machine; purchase of materials and wire-soldering equipment, thin-film deposition system for coating
components of detectors, etc.). Manufacturing and calibration of a detector to determine the absolute intensity of IBR-2 neutron beams.
- Development of electronics for 240 measuring channels for acquiring and storing data from the BSD detector of the HRFD diffractometer. Modernization
of data acquisition systems on the REFLEX and GRAINS spectrometers on the basis of new MPD32-USB3 modules and De-Li-DAQ2 modules for acquiring data from
position-sensitive detectors in the raw data transfer mode. Application of digitizers in data acquisition systems, as well as in the equipment of the
test stand for the development and debugging of event selection algorithms for scintillation detectors.
- Installation, tuning and commissioning of CC-3U chopper controller into trial operation on the NERA spectrometer. Installation and tuning
of a remote control system of choppers on the GRAINS and YuMO spectrometers. Modernization of control systems for actuators of spectrometers on IBR-2
beamlines 6à, 811. Installation, tuning and commissioning of a new Fourier chopper on the FSD diffractometer.
