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.
