Raman Spectrometer for monitoring Isotope Exchange Reactions and Energy Transfer in Low Temperature Plasmas

One of the major elements in tritium processing systems is hydrogen isotopes identification and separation. Work with multiple hydrogen isotopes at the is often accompanied by isotopic mixing. Maintaining isotopic purity of tritium is one of the major tasks in new generation Texas Neutrino Mass Experiment (NEXTEX). We developed unique Raman Spectrometer capable of detecting hydrogen isotopes T2, HT, H2, D2, TD and H2 at pressures near 10 Pa with signal-to-noise ratio better than 2 during minutes long observations. This spectrometer is capable of distinguishing traces of numerous isotopomers at partial concentration as low as 1:4000 and can be also used as a medical diagnostic tool. Additionally I will discuss some aspect of our Coherent Raman Spectrometer and its ability to measure molecular kinetics in low temperatures plasmas.
