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.
