TOMSK, April 6. /TASS/. Scientists at Tomsk Polytechnic University, funded by a grant from the Russian Science Foundation, will develop a coating made of trinobium material, which will make it possible to make the cheapest and most efficient resonators — parts for the operation of particle accelerators, for example, the Large Hadron Collider, the press service of the university told reporters.
"Resonators are one of the key elements of accelerators, today they are mainly made from expensive niobium, so researchers are looking for new materials for resonators. We propose to apply on a more budgetary basis, for example, copper, a thin coating of triniobium stannide. This is a promising material, but it has a drawback — it is fragile, while it is known that defects in the coating can lead to the loss of superconducting properties in high-frequency fields, to solve this problem we will try several new approaches. Obtaining high-quality, homogeneous trinobium coatings for resonators will reduce the cost of their manufacture and, in theory, increase the efficiency of particle acceleration," the head of the scientific group, Alexei Shevelev, was quoted by the press service as saying.
Scientists intend to carry out trinobium processing of resonator prototypes for the future generation of domestic and foreign accelerators and test them on measuring stands under superconducting conditions. The results of the work can be claimed in scientific centers where particle accelerators are located — NICA complex in Dubna, Budker Institute in Novosibirsk, DESY in Germany, KEK in Japan, CERN in Europe, etc.
It is reported that all grants were won by three research groups of Tomsk Polytechnic University, the total amount of support for three projects will reach 54 million rubles. Thus, a scientific group headed by Aleksey Mazurov, Professor of the Department of Geology of TPU, with the support of the Foundation, will conduct a large-scale fundamental study of ancient sedimentary deposits of iron ore or marine iron ore. Currently scientists do not know how they were formed, and the answer to this question will help to better understand the origin of not only iron deposits, but also genetically related mineral deposits.
The third group, led by Professor of Butakov Scientific and Educational Center at TPU Geniya Kuznetsova will study the features of the spread of fires in enclosed spaces. Scientists will develop experimental techniques to determine the effective conditions for extinguishing such fires. In order to do so, they plan to use high-speed recording systems, laser technology, tracking complexes and sensors. The results will help create a database of combustion sources and scenarios for the spread of fires in rooms, as well as new types of sensors for detecting fires.
