In this work, commercially pure niobium (cp Nb) was selected to study its electrochemical
behaviour in artificial saliva with several concentrations of fluoride ions (F−) over a range of …

The majority of niobium cavities for superconducting particle accelerators continue to be
fabricated from thin-walled (2–4 mm) polycrystalline niobium sheet and, as a final step …

In this work, the passivation behavior of Nb in acid fluoride-containing solutions with pH of 4,
5 and 6 was investigated. Both electrochemical measurements and surface characterization …

Foreword from author; When I joined the CEA Saclay SRF group in 1989, my initial
background was physical chemistry and surface science, which I completed later on with …

Electropolishing (EP) is applied to niobium (Nb) superconducting radio frequency (SRF)
cavities, which are used in particle accelerators for their surface treatment. The EP process …

Superconducting rf (SRF) technology is evolving rapidly, as are its applications. While there
is active exploitation of what one may call the current state-of-the-practice, there is also rapid …

This work presents a highly precise chemical etching process designed to achieve
controlled modulation of the formation and removal of the oxide layer on the surface of …

For the construction of the international linear collider, mass production of niobium (Nb)
superconducting cavities is essential. In the surface treatment of the Nb cavities, on-site …

Electropolishing (EP) is a standard process for the treatment of the interior surface of
niobium (Nb) superconducting radio-frequency (SRF) cavities used in particle accelerators …

A detailed study on vertical electropolishing (VEP) of a 1.3-GHz single-cell niobium coupon
cavity, which contains six coupons and four viewports at different positions, is reported. The …
