The staff of the Department of Applied Nuclear Physics of the Institute of Physico-Technical Intelligent Systems of the National Research University MEPhI has developed a unique stand for neutron radiation spectrometry and dosimetry, which can be used both to ensure radiation safety in the nuclear industry and for scientific purposes.

The main feature of the stand is that it includes three neutron radiation detectors based on different physical principles: a detector based on a diamond sensing element, a multilayer dosimeter-spectrometer based on a zinc sulfide and lithium fluoride scintillator (ZnS(Ag)+6LiF) and a spectrometer based on an organic scintillator. Due to this, the development is able to measure the characteristics of the neutron field in a wide energy range from 0.025 eV to 15 MeV and a dose rate range from 10 mSv/h to 10 kSv/h. Thus, the experimental stand allows for a comprehensive analysis of the neutron field of all existing "ground-based" sources of thermal and fast neutrons. The signals from all three detectors are processed by a computer.

The new stand can be used for dosimetry and spectrometry of neutron radiation in the operation of medical, nuclear power, thermonuclear and accelerator installations, to ensure nuclear safety and nuclear non-proliferation, for radiation metrology and registration of fast-flowing processes in scientific experiments.

The stand will be presented at the international military-technical forum "Army", which will be held at the Patriot Convention and Exhibition Center from August 12 to 14.

Recall that last year, IFTIS of the MEPhI Research Institute presented at the Army forum a block of plasma focus emitters for testing scientific equipment; details are here.
