Abstract
Suitable analytical methods need to be developed and tested for process control and reliable tritium accountability within the fuel cycle of a fusion reactor. The analysis of all hydrogen isotopes and isotopically labelled methanes were taken as an example to examine the laser Raman spectroscopy combined with mass spectrometry using an Omegatron. The Omegatron is suitable for the analysis of all hydrogen isotopes and the stable helium isotopes. The limits of the applicability of this mass spectrometer were shown by the analysis of mixtures of deuterated methanes. The Omegatron was also used for experiments of the radiochemical `Wilzbach` exchange reaction between tritium and methanes. A laser Raman spectrometer for the analysis of gaseous mixtures containing tritium was designed and build using the single components. A tritium compatible, metal sealed Raman cell with windows of high optical quality and additional measures to minimize stray light was successfully employed for the first time. The Raman spectra of the hydrogen isotopes were measured in the pure rotation and in the rotation vibration branches and used for calibration. The deuterated methanes (CH{sub x}D{sub 4-x}) were investigated by Raman spectroscopy, the measured wavenumbers assigned to the corresponding normal vibrations and the wavenumbers of the rotational
