Anything bulk niobium can do, thin films can do better. At least, that’s the hope of Jefferson Laboratory scientists, who are currently exploring a method that would allow them to create customisable thin niobium films.

Elegant and inexpensive, the second-sound detection system developed at Cornell University helps scientists triangulate the location of hard-to-see accelerator cavity flaws. Helium helps.

Scientists at KEK in Japan are currently developing a 'distributed radiofrequency system' for delivering radiofrequency power to the ILC accelerating cavities. An alternative solution to the 'klystron cluster scheme', this powering method accommodates the ILC’s new one-tunnel design.

... we plan to set an average operating gradient of 31.5 MV per metre for the 14560 cavities mounted in the 1680 cryomodules of a 500-GeV ILC.

At the ILC, roughly 16,000 superconducting RF cavities made of pure niobium will accelerate electrons and positrons to the high energy of 500 GeV. Each one-metre-long cavity consists of nine cells, polished to provide micrometre-level surface smoothness and absolutely no impurities. The inside of the cavities need to literally sparkle since any surface blemishes or dust could cause them to lose their superconductivity, making them unable to sustain the electric field needed to accelerate particles. ILC scientists around the world are devoted to trying to get a higher yield rate for producing good-quality cavities by improving surface treatment methods and inspection procedures. A group of scientists from Kyoto University and KEK jointly developed the novel inspection system to take a close look at the interior surface of the cavities, and produced remarkable results.
