Project summary

Objective of the project is elaboration of a principally new technology for fabrication of powders for scintillation materials; fabrication of standard and new high performance nanocrystalline scintillation materials - titanates; preparation of pilot samples of nanocrystalline scintillators and investigation of their properties; elaboration of new production schematic model for the fabrication of scintillators using closed technological cycle for the fabrication of scintillators.

Another objective is elaboration of an original installation for hot pressing of nanocrystalline scintillation powder materials.

Novelty of the project:

1. New nanocrystalline scintillation materials;

2. New technology for the fabrication of nanocrystalline standard and new scintillation materials;
3. Original installation for hot pressing of nanocrystalline scintillation powder materials.

Nanotechnology provides the unique prospect of preparation of scintillation elements in an extremely fine structural condition instead of the commercially applied expensive single crystal route. The basic concept is built on the chemical synthesis of complex inorganic compounds of Lu, Cd, and Y and metaloorganic compounds of Si, W, Mo, Al and Ti to form scintillators of specific compositions via low-temperature thermochemical synthesis. It is generally impossible to obtain scintillator materials of such a variety of compositions via current state-of-the-art technology. Furthermore, since the technology of single crystal growth is extremely difficult and complex, currently yield of useable product is rather low ~15-50%. Therefore production cost of single crystal scintillators is high limiting their commercial application. The proposed technology will not only provide an easy technique to test candidate materials, further broadening this critical field, but will also provide an efficient and commercially viable means of producing cheap scintillator materials. The use of this technology, will therefore, enhance the range and spectrum of applications of gamma- and X-rays in computer tomography, positron emission tomography, in the physics of nuclear and elementary particles, nuclear reactors, radiation control, research of geophysical developments, customs control devices, for the prevention of acts of terrorism, etc. We propose that this approach will not only create a new class of cheap, highly efficient scintillators based on titanates such as Lu2TiO5, Lu2Ti2O7, etc., but also have an unparalleled impact on the development of scintillator material in the future.

Scientific and practical value of the project:

1. Elaboration of compositions of standard and new high performance nanocrystalline scintillation materials.

2. Broadening of the area of application and increasing of the resource of scintillator pieces; in particular, increase of an opportunity to create a new generation of scintillation materials - titanates.
3. Design and building of original devices for hot pressing of nanocrystalline powder materials.

The goals will be achieved on the ground of scientific elaborations, experience and equipment installed at the Technical University of Georgia as applied for creating nanocrystalline composite materials and the instruments for their testing.

Support of the project will be of a great social economic significance for Georgia. First, scientific potential of a group of leading scientists who were basically involved in Defense Institutions of the USSR, will be directed to the creation of peaceful production at minimal financial expenditure necessary for the solution of such kind of problems. Second, realization of the project will further progress in the field of science and economy of the country via development of new scientific-technical direction and industry of the product competitive at the world market.
