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 …

Much interest was generated in the mid to late 1990s in an alternative cavity surface
processing technique called centrifugal barrel polishing, that mechanically polishes the …

To develop cavity inspection and repair techniques is important for quality control of the
superconducting rf cavity to get more better yield for high accelerating gradient. A high …

As reported previously at the Berlin workshop, applying the JLab standard ILC
electropolishing (EP) recipe on previously buffered chemical polishing (BCP) etched fine …

We report on the progress of ILC high gradient cavity R&D at Jefferson Lab since the Berlin
conference. The optimal cavity processing recipe has been developed and applied for …

One of the major goals of ILC SRF cavity R&D is to develop industrial capabilities of cavity
manufacture and processing in all three regions. In the past several years, Jefferson Lab, in …

Optical inspections on superconducting accelerating tubes have been playing an important
role on improving their accelerating gradients. Instead of treatments on whole cavity inner …
