The Scientific Center for the investigation of the nature of luminescence and the mechanisms for creating radiation defects in alkali-halide crystals (AHC) with a symmetry of the lattice lowered was organized on the initiative of K.Sh. Shunkeyev in 1984. With the direct support of academician Luschik Cheslav Bronislavovich, the laboratory acquired a scientific direction and was equipped with the necessary instruments for creating experimental facilities for absorption, luminescence and thermoactivation spectroscopy, as well as recording ion conductivity and thermostimulated crystal depolarization currents as the lattice symmetry decreases.
An universal cryostat, developed by us, was manufactured in the design bureau of the Institute of Physics of the University of Tartu of Estonia.
Directions of scientific research:
- Experimental studies by absorption, luminescent and thermoactivation spectroscopy methods, as well as recording of ionic conductivity and currents of thermally stimulated depolarization of crystals with decreasing symmetry of the lattice.

Material and technical base
Experimental installation for luminescence spectroscopy
A multifunctional spectral complex scans spectra using a high-power monochromator MSD-2 and a photomultiplier tube type H 8259 by «Hamamatsu» operating in the photon counting mode controlled by special programmes SpectraScan and ThermoScan in a wide interval of spectrum 200÷850 nm and temperatures 85÷400 K subject to uniaxial deformation (ε=0.1÷1.2%) under high technical vacuum.
Based on digital technology under low temperature deformation the following spectral characteristics of AHC are registered:
- luminescence by X-ray (LXR),
- tunnel luminescence (TL),
- Thermal stimulated luminescence (TSL),
- time scan of tunnel luminescence,
- TSL spectra.
Scanning speed of spectra: 50, 25, 10, 5, 1 nm/s.
Irradiation of crystals is carried out from X-ray installation RUP-120 in mode 3 mA, 120 kW..
Cryostat for the deformation of crystals at 80÷500 K is patented in the Republic of Kazakhstan
The cryostat allows measurement of luminescence-absorption characteristics of crystals (spectra of absorption, excitation, emission, X-ray luminescence, thermal stimulated luminescence, tunnel luminescence, thermal stimulated depolarization of currents and ionic conductivity) as before deformation and under the action of elastic and plastic deformation of various degrees (0 ≤ ε ≤ 10%) in a wide temperature range (80÷500 K).
Thermoluminescent dosimetry system
The Harshaw 3500 model is a modern reader designed to measure the light output of thermoluminescent elements. This system is intended for recording and analyzing high-temperature luminescent properties. Through the study of thermally stimulated luminescence (TSL), it allows researchers to characterize the thermal stability of materials and recombination processes.
The system uses a contact heating method for thermal excitation. A feedback control system integrated into the heating planchet ensures precise temperature regulation with an accuracy of ±1 ºC. The registration temperature range is 295–873 K (approximately 22–600 ºC), and the heating rate can be set between 1 and 10 ºC/s. By adjusting the heating rate, one can monitor the temporal distribution of luminescent signals, aiding in the identification of various types of defects.
The WinREMS software automates the measurement process and enables the processing, analysis, and storage of the acquired TSL glow curves. The system also includes a highly stable LED reference light source integrated into the photomultiplier tube (PMT) module. This reference signal can be read by the operator at any time, even during active measurements.
Experimental installation on thermal activation spectroscopy
The installation makes it possible to record ion conductivity and thermostimulated depolarization currents of crystals in a wide temperature range from 196°С to 350°С in the combination of a specialized cryostat that performs the regime of temperature and low-temperature deformation. The installation is assembled on the basis of the standard vacuum unit VUP-4. The level of technical vacuum is achieved by two steps: forvacuum pumping up to 10⁻² Торр and then - diffusion pump up to 10⁻⁵ Torr.
In the current spectra of thermos-stimulated depolarization of alkali halide crystals, polarization currents of dipole defects are detected. Such a method for recording the polarization dipole currents of alkali-earth metals in a wide temperature range (80÷500 К) after the action of plastic deformation creating a divacancy is designed as an application for an invention.
The technical result achieved in the present invention is a method for recording polarization dipole defects in alkali-halide crystals and determining their maximum disorientation temperature from the peaks of the current spectrum of thermally stimulated depolarization performed by linear heating of the crystal in the temperature range from 80K to 500 K.
Thus, the experimental setup makes it possible to register the ionic conductivity and thermally stimulated depolarization currents in a wide temperature range (80-500 K) of dielectric materials, which are alkali-halide crystals.
Experimental installation of luminescent spectroscopy based on the SDL-2 spectral complex
Spectral complex by luminescence spectroscopy based on SDL-2 with two sources of excitation (photo- and X-ray) using exciting monochromator MDR-12 and registering monochromators MDR-23 (MSD-2) allows realizing for automatic registration of spectra of all types of luminescence of AHC in the photon-counting mode using PhEM of the company of «Hamamatsu» in a wide interval of spectrum.
For solving these problems, a continuous light source is used - xenon lamp AXBL-150, emitting a continuous spectrum from 200 nm to 850 nm. The reliability of scanning the luminescence spectra of the AHC directly depends on the light source, which provides an intense and stable luminous flux.
For this purpose, the xenon lamp, which is part of the standard spectral complex, was replaced with a Hamamatsu EQ-99X LDLS laser source, emitting a highly stabilized and intensive luminous flux in the spectral range of 170-2100 nm, to ensure high-precision registration of the luminescent characteristics of the AHC.
Two types of ionizing radiation sources are provided in the spectral complex - ultraviolet light (S) with photon energy, corresponding to the excitation of anionic excitons in the AHC and X-ray radiation.
Spectral complex in the spectral range from 180 nm to 1200 nm with a replaceable diffraction grating allows to record the spectra of optical absorption, excitation and radiation of substances (crystals, liquids and gases) and to trace the kinetics of these spectra in time.
Experimental installation for absorption spectroscopy
The automatic recording spectrophotometer allows analyzing the transmission and optical absorption spectra of substances (crystals, liquids, and gases) in the spectral range - 190-900 nm (6.5-1.4 eV). The device is equipped with a two-beam optical scheme in contrast to standard spectrophotometers. The built-in computer program provides scanning of spectra in a given spectral interval with different speeds and allows the development of time kinetics. It should be noted the peculiarity of the device that the optical density of substances is registered up to 4 units, when the existing analogous devices have only up to 1.4.
Innovative Electrohydraulic systems KID 21
The installation realizes a controlled high-voltage source with a storage capacitor that is cyclically discharged through special electrodes placed in a liquid medium. For creating the device, scientists of the Faculty of Physics and Technology have solved a number of problems to project and manufacture, on the modern element base of the electrical circuit of the device capable of withstanding pulsed currents of hundreds of kiloamperes for a long time, which occur when the storage capacitor is discharged.
One of the main directions of using the plant by the customer is the elaboration of an electrohydraulic method for enrichment diatomite raw materials, the essence of which is the conclusion of ore fractions using the energy of a plasma that occurs during a short and very powerful electric discharge in a liquid medium.
Computer Park
The computational modeling of processes in the HPC system is carried out on a Supermicro server. For this purpose, Supermicro-X11 series motherboards and Intel Xeon Gold-6130 processors are used. These processors are designed for cloud computing applications, including data centers, high-performance computing (HPC), high-end workstations, and storage networks.
The system enables the execution of complex calculations, efficient management of parallel processes, and the handling of large volumes of simulation data. As a result, the accuracy and reliability of numerical modeling of physical processes occurring in the HPC system are significantly enhanced.
