This document concerns the proposal for a new diagnostic to be installed in the SPIDER ion source which would enable in-situ measurements of caesium adsorption rate. The motivations for this new diagnostic are the following: - Attempt to measure in-situ the desorption rate of various Cs-composites formed at surfaces inside the source - Verify the influence of a hydrogen atmosphere, and of a plasma discharge, on the chemical properties of the surfaces - Measure the amount of Cs deposited at a specific location inside the ion source - Verify the cumulative effects of many days of Cs evaporation and plasma discharges.
