Today, the global growth in energy demand has led to an active development of research in the areas of its production, storage, and use. The progress achieved in energy production technologies is not sufficient to fully meet the existing demand. The dwindling reserves of fossil fuels have prompted significant efforts to explore the use of hydrogen (H2) as a clean energy source. The use of H2...
The Neutron Activation Analysis (NAA) Group at the IREN research facility, Frank laboratory of neutron physics (FLNP) JINR do determination of the elemental composition of samples of different origin. Several methods are used for experiments, including neutron activation and X-ray fluorescence (XRF) analysis. Investigation of the elemental composition of 17 ceramics pieces found on the...
L10 FePt is expected to exhibit excellent hard magnetic properties even when its size is as small as 3 to 4 nm, due to its large magnetic anisotropy. Therefore, much attention has been placed on fabrication and magnetic properties of nanostructured L10 FePt both from scientific and technological interests. In this work, FePt nanoparticles were obtained by pulsed plasma in liquid method from...
Modern photodetectors, such as silicon photomultipliers (SiPM), are widely used in high-energy physics. In particular, for the near detector of the JUNO experiment, it is planned to use ~250,000 SiPMs, which will be grouped into matrices (~4000 pcs). These photodetectors will be used to register the light that is emitted as a result of the interaction of neutrinos and the detector's...
The Deep Underground Neutrino Experiment (DUNE) is an international experiment for neutrino science and proton decay studies. DUNE will consist of two neutrino detector complexes placed in the world’s most intense neutrino beam. The Near-Detector complex will track particle interactions near the source of the beam, at Fermilab in Batavia, Illinois. The core component of the DUNE Near-Detector...
TAO is one of the two liquid-scintillation detectors of the JUNO neutrino experiment (China).
TAO will be a sphere with about 2.5 meters diameter, filled with a liquid scintillator.
The TAO entire area will be covered by about 250,000 SIPMs (silicon photomultipliers).
All SiPMs need to be carefully tested.
The territory of East Kazakhstan, including Tarbagatai and Zaisan, have been important ethnocultural centers of various tribes and peoples since ancient times. Since 2003, research has been carried out on the Shilikti monuments located in the Zaisan district of the East Kazakhstan region. During this time, four large and one medium and 20 small burial mounds were studied by excavations. East...
Heterostructures of high quality А3В5 arsenides with a quantum well based on In-Ga1-уAs exhibit high mobility of a two-dimensional electron gas and are actively used in microwave heterostructure electronics. In the heterostructures, the current-conducting layer is very thin — of the order of 10–20 nm, enclosed between wide-gap barriers; therefore, the radiation physics of such structures may...
A large number of experimental facilities are being built in the world. They will work in the fields of powerful ionizing radiation. Applied studies of the radiation resistance of materials for them is one of the most important problem. The irradiation facility of the IBR-2 reactor is designed for conducting radiation resistance studies. The length of the irradiation facility is ~8 meters. Due...
The aim of the report is to demonstrate the capabilities of developed small field of view visualization system for gamma radiation sources. The measured system characteristics indicate the possibility of using it in preclinical studies on small animals. The results of tomographic studies on calibration phantoms are presented.
The developing of more technological and less expensive methods of obtaining materials with controlled functional parameters is an actual task of scintillation materials science. Significant prospects in this direction are opened in the creation of composite materials based on microcrystalline scintillation powders, which have a number of advantages in comparison with single crystals, such as...
The implantation of silicon nitride with carbon ions stimulates the formation of additional emitting centers, which are appearing growth points for silicon nanoclusters. Moreover, this method makes it possible to set the sizes of nanocrystals, change their concentration, as well as the properties of the "nanocluster - matrix" interface. All of the above makes photoluminescence controllable and...
