Neutron-diffraction methods are widely used for analyzing condensed matter, offering valuable insights into the internal structure and dynamics of the materials under study. The creation of new high-flux neutron sources to study promising materials and various biological systems places special demands on the operating parameters of detector systems. A new generation of position-sensitive thermal-neutron detectors should have record-breaking characteristics in terms of spatial and time resolution with a high detection efficiency. This work focuses on the exploration of new solutions for implementing detector systems in neutron-scattering stations, specifically examining the potential use and expected performance characteristics of 10B resistive plate chambers (RPCs) for detecting thermal neutrons.

In this paper, we present a prototype of a two-coordinate position-sensitive detector based on a small-area 6LiF/ZnS(Ag) scintillator fabricated using square-section spectrum-shifting optical fibers. The size of the square active area of the detecting surface (96 × 96 mm) corresponds to 16 channels along the X axis and 16 channels along the Y axis. The obtained neutron-detection efficiency is 8%.

Lithium–indium diselenide (LiInSe2) is a new semiconductor material, sensitive to the thermal neutrons. LiInSe2 compound was synthesized from Li (99.99%), In (99.999%) and Se (99.999%). The growth of LiInSe2 single crystals was performed using the vertical option of Bridgman–Stockbarger method. The crystals were characterized using the electrical conductivity and optical spectroscopy methods. Stoichiometric composition of the LiInSe2 was confirmed by the high precision chemical analysis, as well as by X-ray diffraction. Compact 252Cf neutron source with the activity 6.3 × 105 n/s allowed measuring amplitude characteristics and defining the optimal operating voltage for neutron detection. Time-of-flight neutron spectra were measured at the fast pulsed research reactor IBR-2 at the Joint Institute for Nuclear Research. [ABSTRACT FROM AUTHOR]
