Carrying out of test loading of CM-201 moderator chamber with frozen mesitylene pellets during reactor power operation. Tests of an optical sensor used to control the movement of pellets and count them during their transportation to the moderator chamber at a special test stand of CM-201. Current modernization and maintenance of CM-202. Determination of release of radiolytic hydrogen in CM-202 moderator chamber using chromatographic equipment during reactor power operation.

  • Investigation of radiation resistance of materials at the radiation research facility. Development of a system for moving highly active samples using a robotic manipulator.

  • Optimization of parameters of spectrometer components by Monte Carlo simulation.

  • Assembling of a horizontal/vertical cryostat with a superconducting magnet and variable temperature range of 4-300 K; start-up of the cryostat in the cooling mode of the magnet in a heat-exchange gas; carrying out of preparatory work for the installation of the cryostat at the DN-12 diffractometer.

Development of event selection algorithms for scintillation detectors and their debugging at a test stand with a new MPD32 data acquisition system. Adaptation of MPD32-USB3.0 data acquisition system for other types of detectors.

  • Modernization of control systems of actuators of HRFD and FSD spectrometers. Installation of diaphragms for collimation of neutron beams in the spectrometers. Installation, adjustment and putting into trial operation of -3U chopper controllers as a part of a control system for choppers on GRAINS and REFLEX spectrometers.
