Local and International collaboration

Local collaboration

On the basis of performed fundamental investigations, the applications of developed methods and equipment have been realised for local non-intrusive diagnostics and control of temporal evolution of gas parameters, such as composition, temperature, density, energy distribution over the internal degrees of freedom.

In co-operation with the Physics Instrumentation Center, computer-controlled Nd:YAG-based narrowband scanning CARS spectrometers have been developed and manufactured.

They were installed in various institutions in Russia and joint experiments have been done:

Central Scientific Research Institute of Mashinery (TsNIIMASH) Joint experiments: Temperature measurements in a plasmatron flow.

Design Bureau "ALMAZ". Joint experiments: Energy distribution among vibrational and rotational degrees of freedom in electric discharges.

Central Aerohydrodynamic Institute (TsAGI). Joint experiments: Energy distribution among vibrational and rotational degrees of freedom in rarefied supersonic flows. Temperature measurements in supersonic hydrogen-air combustion.

Central Institute of Aviation Motors (TsIAM) Joint experiments: CARS thermometry in combustion chambers of the aircraft engines.

Another long-term joint research collaboration is in progress with P.A.Hertzen Moscow Research Oncology Institute. This collaboration is devoted to development of fluorescence diagnostics of malignant tumors and to Photodynamic therapy of cancer. Both methodical aspects and research equipment is being developed.

During 20 years of research in the field of optical spectroscopy often there appeared a need in some sophisticated equipment either not available on the market at all, or being extremely expensive. So, several unique devices have been designed, manufactured and tested in our Department. Now they are commercially available from Cluster Ltd - a company, established by the General Physics Institute in 1993.
