Users can take a virtual tour through the European XFEL tunnel, currently under construction, walking through the newly planned facilities to get an idea of its space and future working conditions. The nine-cell structures of pure niobium are designed to speed up the electrons at DESY's FLASH, the European XFEL, and the ILC. The picture was taken in DESY’s IPP stereo projection room, where it is possible to project and view three-dimensional models on a 1:1 scale.

Designing and fabricating an optimal accelerating cavity is not so simple. There are two important parameters scientists are looking for: the gradient of 35 megavolts per meter (MV/m) and the quality factor (Q0) of greater than 0.8×10^10. A Japanese cavity now fulfilled those requirements for the first time at a test which took place at the Superconducting radiofrequency Test Facility (STF) at KEK, adding momentum towards future mass production.

A 1.3-gigahertz TESLA-type nine-cell niobium superconducting cavity, named PKU3, as the third nine-cell cavity fabricated by the superconducting radiofrequency (RF) group at Peking University, Beijing, China, achieved an accelerating gradient of 28.6 megavolts per metre (MV/m) at an unloaded quality factor of 4×109 in its second vertical test at Jefferson Lab (JLab), USA on 9 August 2010. This cavity is the first nine-cell cavity with end group components in China reaching a gradient usable for the ILC.

A 1.3-Gigahertz low-loss type large-grain nine-cell superconducting cavity called IHEP-01 produced at the Institute of High Energy Physics (IHEP) in Beijing, China, achieved an accelerating gradient of 20 Megavolts per metre in its first vertical test at KEK on 1 July. This may not be the design gradient yet, but it marks an important progress on the research and development of superconducting radio frequency (SRF) technology in China.

(...) Taking all ILC cavity tests into account, a globally-based pattern of achievement and success emerges, giving confidence that we will meet or even exceed the forward looking-goal we set for ourselves at Snowmass in 2005.
