Electropolishing experiments on niobium samples are carried out in Saclay:
-	to study the bath aging, its origins and the consequences on the polishing performances,
-	to highlight the influence of parameters such as temperature and acids concentrations (hydrofluoric and sulfuric).
Some mixtures with different concentrations have already been investigated. Intensity as a function of time, surface states and polishing speed were considered at different potentials.
