Design, Manufacture and Verification Testing of an In-Line Probe for a Raman Spectroscopy

he intention of this work is to develop a Raman spectroscopy probe which is assessed as being suitable for use in high concentration gaseous tritium applications, which can be readily manufactured and for which its baseline performance characteristics (in an inactive environment) are known. In doing so, the STEP programme aims to achieve a Raman probe which can later be tested in a tritium environment and which is readily available for future programme requirements and other fusion/tritium applications at hardware cost, without the need for specific development costs.
