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.
