During last period of research in frame of the acting ISTC Project 25 "Muon Catalyzed Fusion and its Applications" it was recognized that the isotopic molecular composition of triple H/D/T mixture of hydrogen isotopes is the critical parameter for efficiency of the muon catalyzed fusion.
The main objective of the proposed subproject is the study of isotopes exchange in triple H/D/T mixtures and measurements of equilibrium constants in wide range of concentrations at low temperatures.
Raman scattering (RS) will be used as principal experimental method for quantitative analysis - it is necessary to develop as special equipment, so the methodology of RS analytical application for the low temperature hydrogen isotopes mixtures in gas and liquid phase, containing high amount of tritium.
• exact measurements of equilibrium constants and rates of isotope exchange in triple H/D/T mixtures of hydrogen isotopes at low temperatures;
• measurements of constants of Raman scattering on isotopic substituted hydrogen molecules in gas and liquid phase;
• development of new RS spectrometer for quantitative analyses of liquids and gases.
The pilot specimen of the RS spectrometer could be interesting itself as a new type of commercial analyzer. Results could be interesting to institutions, involved in R&D programs in laser spectroscopy, analytical chemistry and in the field of environment monitoring.
Obtained constants are widely applicable in fusion research and technology, especially in the D/T fusion fuel cycle and tritium technology in large scale fusion programs like ITER or TFTR; in hydrogen isotopes separation; and in other chemically hydrogen related technologies.
