Possibility of analyzing deuterium-tritium gas mixtures using a time-of-flight mass spectrometer

The use of a time-of-flight mass spectrometer, whose ion source and detector operate in a synchronous regime, is proposed for the chemical and isotope analysis of gas mixtures containing radioactive tritium. The experiments performed confirm that the detector background current caused by tritium β electrons scarcely influences the signal-to-noise ratio and does not diminish the accuracy of analyses.
