Design Implications for Laser Raman Measurement Systems for Tritium Sample-Analysis, Accountancy or Process-Control Applications

In this paper we discuss the implementation of Raman spectroscopy for compositional analysis, and monitoring and control of tritium-carrying gas flows. Specifically, we discuss how the criteria for the detection and handling of tritium impact on the conceptual design and actual system suitability and performance in applications such as the KATRIN experiment or the ITER fuel cycle, which require real-time, in-line monitoring and control.
