Project summary

An aim of the project is the development and creation of powerful exciplex sources for ecology range of problems. In particular, one of the key purposes is the decomposition of adverse organics. Other possible applications are the sterilization of water from bacteria and the disinfection of solutions in motor vehicle industry, these sources can be widely used in microelectronics, medicine and biology, for curing lacquers and paints and solving environmental problems (decomposition of toxic wastes).

There are many kinds of radioactive wastes mixed with organics. For instance, wastes of medicine or radioactive production and so on. The radioactive reclamation technology used in USA consists of next steps. Organics with radioactive wastes are placed to the water with H2O2 additions. The UV (l < 250 nm) radiation distract H2O2 molecules to the OH radicals which efficiently extract H atoms from organics. After this organics are destroyed, only fallout remains which have sufficiently compact sizes compared with original ones and which can be utilized more simply. The KrCl lamp is optimal in this case.

There are also, for instance, some problems in water purification. In motor vehicle industry the metal details are worked by special solutions which should be disinfected before dumping. The solutions in CD production, especially in warm countries, should be sterilized from bacteria. The UV lamps can be used in these fields.

The following problems are planned to be solved during the work under the present project:


Al. Search for new efficient optical media and optimization of known media.
A2. Experimental investigation and theoretical simulation of kinetic processes in optical media.
A3. Development of powerful efficient sources of spontaneous radiation in the UV, visible and IR spectral ranges.
A4. Design of new production processes with the use of the powerful sources of spontaneous radiation to be developed.

Realization of the project provides both investigation of conversion of energy transferred from nuclear radiation, self-sustained discharges and electron beams to optical radiation and integration of production processes based on the principal advances of modern world science into practice of safe generation of high-quality light energy. The project realizationunakes possible development of powerful sources of spontaneous radiation with high operating parameters and commercial models of the sources for social-orientated market. Various gaseous media will be investigated to found new promising light sources with efficiency more than 10%. The powerful lamps other than xenon and mercury ones for practical reclamation (mainly for radioactive reclamation) will be developed. In particular, glow discharge pumped KrCl and XeCl excilamps with output average power over 1 kW is planned to create.

Potential role of foreign collaborators

Study of the radioactive properties of the plasma pumped by nuclear fusion fragments, e-beam and electric discharges are planned to be made in close cooperation with world scientific association. The project results are approved at international conferences and in discussions during visits to national laboratories of Russia, USA and Germany.
